My baby is 5 weeks old and the last couple of days has been taking less at quite a few of her feeds, she usually takes 3oz from a 4oz bottle (sometimes closer to 4) but the last two days it's often been a battle to get her to take 2oz before falling asleep! She's still having wet nappies as usual.
When would you be concerned?
Could it be related to some sort of growth spurt or something, although I'd have expected her to eat more in that case?
