i let my lo sleep as long as she wants since day 1. she wakes every 2-4hrly to feed, if baby is healthy, gaining weight & not jaundice can just let them feed on demand. i only wake her up to feed if she sleeps longer than 5hrs, otherwise i’ll let her be. she’s now 5w5d old & gaining weight well, gained 1.5kg since birth. pd says it’s fine too :)
