My daughter had jaundice when born and had to have phototherapy and be woken to feed every 3 hours for her first week. For a while now she has been queuing for feeding every 3-4 hours so I stopped setting an alarm to wake her several days ago. Last night (18 days old) she slept from midnight to 7am and I am panicking a bit that it was too long. Is she still too young to sleep this long or is it ok? Should I start setting alarms again? She is formula fed and also given what little I can pump (I have supply issues due to PCOS) if that makes a difference.
