Yes, nursing your baby helps them to sleep more. Breastfeeding helps babies feel more relaxed and content. Nursing is not only an important way for mothers to signal their milk has come in. But also a time of bonding with the baby every day, which every parent needs.
It's a common misconception that babies should not nurse at night because of the risk of falling asleep. And suffocating, though this is generally true for children older than one. But this danger does not exist for an infant under six months old as their reflexes haven't developed yet. And as such, not only will the lactogenic hormones released by breastfeeding help you to express more milk. Which will increase their supply per feeding but those calming elements in breastmilk may encourage your child to drift off to dream land as well.
