Tandem breastfeeding means nursing a newborn and an older child during the same period. You can feed them together, one after the other, or at different times. In the first days after birth, offer the newborn the breast first and feed in response to hunger cues. Use a supported position, check for swallowing and weight gain, and seek lactation help if feeding hurts or milk intake is uncertain.
What Is Tandem Breastfeeding?
Tandem breastfeeding, also called tandem nursing or tandem feeding, is when a parent breastfeeds two children of different ages. It often happens when someone continues breastfeeding an older baby or toddler during pregnancy and then nurses both children after the new baby arrives.
You do not have to feed both children simultaneously to tandem breastfeed. You can nurse the newborn first and the older child afterward, offer feeds at separate times, or sometimes feed them together. According to the Australian Breastfeeding Association, families can choose whichever arrangement works for their needs and comfort.
Tandem breastfeeding is a personal choice. Some families continue because the older child still enjoys nursing, while others find it helps their toddler adjust to a new sibling. You can also decide to reduce or stop the older child's feeds if nursing both children becomes uncomfortable or difficult to manage.
How to Tandem Breastfeed Step by Step
1. Prepare a comfortable feeding space
Choose a quiet place where you can support both children without straining your back, neck, or arms. Keep water, a snack, burp cloths, and any items your older child may need within reach. Have pillows or cushions ready to support your arms and back, but do not use them to prop up the newborn without supervision.
If possible, have another adult nearby during the first few attempts. They can help position your toddler, pass you supplies, or take the older child when you need to concentrate on the newborn's latch. Feeding one child at a time may be easier while you recover from birth or learn your new routine.
2. Position and latch the newborn first
In the early days after birth, give your newborn priority at the breast. This helps ensure that the baby has an opportunity to feed frequently and receive colostrum, the first milk produced after birth. La Leche League International discusses prioritizing the newborn during early tandem nursing, particularly when the older child breastfeeds often.
Hold the newborn close to your body, with the baby's head and body aligned and the nose level with your nipple. Bring the baby toward the breast when the mouth opens widely, allowing the chin to touch the breast first. The baby's nose should remain clear, and you should be able to see or hear swallowing during an effective feed.
A deep, comfortable latch is important even when you are also nursing an older child. The NHS guidance on breastfeeding position and attachment explains how keeping a baby's body close and aligned can help the baby attach well and feed effectively. Ask a midwife or lactation consultant to observe a feed if you are unsure about the latch.
3. Decide when to nurse the older child
Once the newborn is feeding comfortably, you can offer the breast to your toddler or older child if you want to feed both at once. Alternatively, finish the newborn's feed before nursing the older child. Both approaches can work, and there is no requirement to coordinate every feed.
Explain the routine to your older child in simple language. For example, you might say that the baby will drink first and that their turn will come afterward. Young children may need reminders and reassurance, especially when they see the newborn nursing frequently.
Which Positions Work Best for Tandem Breastfeeding?
The best position is one that lets you hold the newborn securely, keep the baby's airway clear, and remain comfortable while supporting the older child. Your children's sizes, mobility, and feeding skills will affect which arrangements are practical.
Newborn in your arms, toddler beside you
This is often a manageable starting point. Hold the newborn in a cradle or cross-cradle position, supporting the baby's head, neck, and body. Let the older child sit beside you and nurse from the other side or wait for their turn. This arrangement allows you to focus on the newborn's attachment while still keeping your toddler close.
Football hold for the newborn
In the football hold, the newborn rests along your side, with the baby's feet pointing behind you. Support the baby's shoulders, neck, and body while guiding the mouth toward the nipple. If the older child is nursing simultaneously, they may sit on your other side or across your lap, provided you can maintain secure support for both children.
Feeding both children side by side
Some parents find it comfortable to feed both children while reclining or lying on their side. However, a position that works with an older child may not be suitable for a newborn unless the baby's head, neck, and airway remain well supported. Ask a lactation professional to demonstrate safe positioning if you are unsure how to manage both children together.
Never prop up a newborn to nurse hands-free or leave the baby unattended during a feed. If you become sleepy, change to a safer arrangement with help from another adult rather than continuing to feed in a position where you might fall asleep with the baby.
How to Make Sure Your Newborn Gets Enough Milk
The newborn's feeding needs should guide your routine, particularly during the first weeks when milk supply and breastfeeding skills are being established. Newborns commonly breastfeed at least eight to twelve times in 24 hours during this period. Allow the baby to feed in response to hunger cues rather than delaying a feed because the older child wants to nurse.
According to the US Centers for Disease Control and Prevention (CDC), signs that a newborn is getting enough milk include frequent feeds, visible or audible swallowing, adequate wet and dirty nappies, and steady weight gain. Your baby's healthcare professional can assess feeding and growth over time.
Signs that breastfeeding is going well
- Your newborn latches onto the breast and sucks rhythmically.
- You can see or hear swallowing during feeds.
- Your baby feeds regularly and appears satisfied after many feeds.
- Wet nappies increase as expected during the first days after birth.
- Your baby receives routine weight checks and follows an appropriate growth pattern.
Contact your baby's healthcare professional promptly if the newborn repeatedly struggles to latch, you cannot hear or see swallowing, wet nappies are fewer than expected, the baby seems unusually sleepy or difficult to wake for feeds, or weight gain is a concern. These signs need assessment in context, and extra feeding support or supplementation may be needed.
If your newborn is premature, has a medical condition, or needs a specific feeding plan, follow the advice of the neonatal or pediatric team. Do not allow tandem feeding to replace recommended feeds, expressed milk, or infant formula when these are needed to meet your baby's nutritional needs.
Will Your Milk Supply Be Enough for Both Children?
Breast milk production responds to milk removal, and your body may adjust to the needs of both children. However, producing enough milk for two is not automatic. The newborn's age, how effectively the baby transfers milk, the frequency of feeds, and your individual milk supply all matter.
During pregnancy, hormonal changes commonly reduce milk production, and the milk gradually changes toward colostrum as birth approaches. An older child may nurse less often or stop breastfeeding because the amount and taste of the milk change. These changes are particularly important if the older child is still a young baby who depends on breast milk for most or all of their nutrition.
If your older child is younger than 12 months and your milk supply declines, speak with a healthcare professional about whether additional breast milk or infant formula is needed. Children under 12 months generally require breast milk or infant formula as their main milk source; ordinary cow's milk should not replace these feeds. Older children who eat a varied diet may obtain much of their nutrition from food, depending on their age.
After birth, milk production often increases over the following days. Your newborn may feed more frequently as supply develops, while your older child may ask to nurse more often too. If you are concerned about supply, have a lactation consultant assess the newborn's latch, milk transfer, and growth rather than relying only on how full your breasts feel.
What If the Newborn Coughs or Pulls Away During Feeding?
Sometimes, a newborn may cough, gulp, or pull away when milk begins flowing quickly. This can be associated with a strong milk flow, especially when the parent is producing milk for two children. If it happens repeatedly, ask a lactation consultant or healthcare professional to assess the baby's feeding and suggest suitable positions or adjustments to the feeding routine.
Some families find it helpful for the older child to nurse briefly before the newborn is attached, once the newborn's feeding needs and milk intake are being met. This may help manage a forceful initial flow, but it should not delay a hungry newborn's feed or take priority over the baby's nutritional needs during the early days.
How to Manage Tandem Breastfeeding During Pregnancy
Many people can continue breastfeeding during a normal, uncomplicated pregnancy. However, the decision depends on individual circumstances. Pregnancy, Birth and Baby, an Australian government-funded health information service, advises discussing continued breastfeeding with a doctor or midwife if there is a risk of preterm labour, a history of miscarriage, or a multiple pregnancy.
The American College of Obstetricians and Gynecologists (ACOG) notes that available research has not found an increased risk of miscarriage or preterm birth among low-risk women who breastfeed during pregnancy, although the evidence is limited. ACOG also notes an increased risk of anemia during pregnancy when breastfeeding continues. Discuss your medical history, nutritional needs, and concerns with your obstetric care team before deciding what is appropriate for you.
Pregnancy can also make nipples more sensitive and nursing more tiring. Adjust the older child's position, try shorter feeds if that helps, and allow yourself time to rest. Eating a varied, nourishing diet and drinking to thirst can help you meet everyday needs. Seek professional advice if breastfeeding becomes persistently painful, fatigue is difficult to manage, or you are concerned about your health during pregnancy.
Setting Boundaries and Helping Your Older Child Adjust
Your older child may become more interested in breastfeeding after the baby arrives. Seeing the newborn nurse can bring curiosity, a desire for closeness, or a temporary increase in requests to feed. This response can be part of adjusting to a major family change.
You can continue offering feeds while setting limits that suit your family. For example, you may reserve some feeds for bedtime, keep daytime feeds brief, or ask the older child to wait until the newborn has finished. Offer other forms of closeness, such as reading together, cuddling, singing, or spending time with another caregiver.
If you decide to stop breastfeeding the older child, gradual weaning during pregnancy may make the change easier for some families. You do not need to continue tandem breastfeeding if it no longer feels manageable. The goal is a feeding routine that meets the newborn's nutritional needs while also supporting your wellbeing and the older child's adjustment.
When to Ask for Breastfeeding Support
Consider arranging help from a lactation consultant, midwife, or your baby's healthcare professional if you have persistent nipple pain, difficulty positioning both children, concerns about milk supply, or uncertainty about whether the newborn is feeding effectively. A professional can observe a feed, assess the newborn's growth and milk transfer, and help adapt the routine to your family's needs.
Tandem breastfeeding does not need to be perfectly coordinated to work. Starting with separate feeds, prioritizing the newborn, and gradually exploring comfortable positions can make the experience more manageable. You can adjust the arrangement as both children grow and your family's needs change.
