Why do babies fall asleep while breastfeeding?
Nursing can be very tiring on a baby's cheek muscles, which may contribute to their tiredness. This is quite common, especially for newborns as they get accustomed to this new way of obtaining nutrients.
Breastfeeding releases the hormone cholecystokinin in babies, which results in a sleepy feeling. Breast milk also contains other sleep-inducing substances that can help babies develop their own circadian rhythm. Newborns are more likely to fall asleep while breastfeeding than older babies, as they require more sleep at this age.
A poor latch can also cause a baby to lose interest in nursing and fall asleep. If this is the case, try switching the baby from one breast to the other when you feel them nodding off.
Is it different for older babies?
Eventually, all babies will wean from breastfeeding, and as they do, they will start to fall asleep without being breastfed. This also comes with sleep training. By establishing a sleep routine, the baby will learn different techniques to get relaxed and fall asleep more easily. This differs from child to child, so every family can establish their own routine.
Effects of falling asleep while breastfeeding
The sleep-inducing hormones produced by breast milk are higher during the evening, and this, naturally, makes it easier for babies to fall asleep. The act of breastfeeding also makes them feel warm, safe, protected, and loved. Breastfeeding can help babies develop their own circadian rhythm, which will be helpful during sleep training.
On the other hand, your baby may not learn to self-soothe if they are constantly being nursed before bed. You could face a similar challenge with teethers as well. The breast becomes a replacement for self-soothing, and your baby could start relying on being nursed. It can also make weaning more challenging.
If you feel that your baby hasn't had enough to drink and they are falling asleep, try tickling your baby's cheek, toes, or nose. This should lightly rouse them. Keep them engaged by talking to them as you nurse. You can also nurse in a well-lit room (not at night time) and in a seated position rather than lying down. If you're still concerned that they aren't getting enough milk, you can try bottle feeding to gauge how much they consume before falling asleep.
If you feel that your baby's sleepiness while nursing is unusual in any way, contact your physician to rule out any possible condition, such as jaundice.
Reasons to worry when your baby falls asleep while breastfeeding
Falling asleep while nursing can be a sign that your baby is latching poorly and/or not getting enough milk due to a decreased supply. These are both important scenarios to rule out to make sure your baby is getting enough nutrition. If you notice any of the following signs, your baby might not be getting enough milk when they eat:
- Your baby makes a clicking sound while suckling. This is an indication of a poor latch.
- Suckling pace remains the same. Usually, your baby will slow down and swallow after each suck after the initial letdown.
- If your baby seems tense (fist clenched, brows knit) while sleeping, they might still be hungry.
Finding an easy way to get babies to sleep is every parent's dream, but proper nutrition is critical too. During regular check-ups, be sure to speak to your physician about how your baby latches and their sleep routine. Always reach out immediately if you have any concerns.
