is it true that new born baby generally do not sleep beyond 3 hours?

Fully breastfed newborns generally won’t sleep more than 3 hours as breastmilk is easily digestible and they will be hungry. I will latch on demand and my LO will wake every 2 hours for milk. She only slept slightly longer (3-4 hours) at 5 months old. At 9 months, she wakes every 5 hours. If you feed formula milk, your LO might be able to sleep longer but you will still have to wake up to make milk.
