DS is 4.5 weeks. 7 lb 11 at birth, we had a few problems getting going with breastfeeding but quickly resolved, he seems to feed well and is gaining weight according to his centile line (9 lb 4 when weighed 2 days ago).
He is not in general a very sleepy baby - we've had a lot of days (and some nights) where he fights sleep and won't settle. Most nights he's fed at fairly regular 3 hour intervals.
Last night he fed at 11, and was asleep by 11.30. I woke up at 3 thinking 'why hasn't he woken me up for food yet?' Was going to wake him up but then drifted back to sleep myself and next woke at 4.40 - he was still sleeping! I did then wake him up and feed him but he looked like he might easily have slept for another 20-30 min if I hadn't.
Is this something to worry about? 5+ hours between feeds is far too long at this age still, surely?
He also had a long sleep during the day yesterday (following a very unsettled night) of 4 hours, and again we ended up waking him up to feed.
If it's relevant we've introduced Infacol in the last 48 hours, to see if it helps with the discomfort that's obviously been stopping him sleeping (on me, or anywhere else).
So what's the maximum time I should let him go between feeds?
