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.

My mother in law always tell me babies grow by sleeping more rather than eating more. Personally I am the type who will wake my baby up to drink milk if it stretches for too long. If she is within one hour overdue from her scheduled feed I will let her sleep but more than that and I will Try to make noise to see if she will wake up and drink milk. If she wakes and fall back to sleep I will let her sleep. For night time I don't wake her up for feeds because they don't need night feeds actually. They drink in the middle of the night more for soothing purpose.
