My DD2 is 15 weeks and a few days. She is FF for various reasons and eats anything from 5-7 oz in a bottle (as she wishes) and sleeps 12-13 hours through the night. More often than not, she still demands food 3 hourly (now and again she goes 4 if she's drunk a lot). I think this is fine, but I'm being told by several people that she should be going 4 hourly by about 4 months. What is the reason for this? Should I be trying to stretch her to 4 hours? (not that I know how I would!).
My first baby was breast fed until 5 months and I don't think she ever went four hours.
