My LO is 2 weeks old. Currently drinking 80ml to 100ml per 1.5 to 2.5hr. Do you feed on demand or wake your LO up after max. 3 hrs? I am trying to stretch her night sleeping time but worried that she will overslept.

If baby has jaundice still, u MUST wake baby up to feed / latch, at the most can stretch 4hrs. Not possible or feasible to want to stretch night sleeping time - baby is still too young, stomach too small so will get hungry easily - and in case u are wondering, fm or bm will not make a difference to "prolonging" their sleep.
