15 minutes per side is a recipe for baking, not breastfeeding. Not every baby needs 15 minutes per side. Some babies take a full feeding in only a few minutes minutes, and from just one breast per feeding. Other babies may feed for a few minutes off each side. Older, more distractible babies are efficient eaters with more important things to do than state at your chest. They may graze at the boob a few minutes at a time or want to go back and forth from side to side.
Other babies may be boob barnacles and need much longer at the breast. Or they may want to be at the breast for more than just nutrition: teething, growth spurts, you going back to work, developmental leaps, sickness. Being on your body brings healing, comfort and stability while they’re going through all kinds of rapid changes and growth. Being on you for an hour or more is the best medicine to what ails them.
The only time we should be limiting time at the breast is in NICU with premature babies where fatigue is a factor or under the direction of a lactation consultant because of true low supply, tongue tie or other oral motor disfunction while on a triple feeding plan. This would be a temporary plan because of a true lactation issue.
In general, you know baby is getting enough breast milk when you have a pain free latch where the nipple goes in and out of baby’s mouth the same shape. You can hear baby swallow and don’t need to keep them awake at the breast for them to continue feeding. Baby should be making lots of heavy wet diapers and pooping daily or every other day. They also gain weight to their own curve and are a similar size of your unique family genetics.
If your baby typically latches for you, and feeds well, and refuses to latch, they most likely are done. Follow your baby’s lead and get to know their feeding habits. Trust your baby and trust your body. If you’re concerned about how your baby is feeding, schedule and appointment with a breastfeeding expert: an IBCLC lactation consultant.
