My ds now 23wks has been bf pretty much exclusively (very occasional bottle of formula or ebm when I've gone out). It has all gone pretty well and he has been sleeping through the night for a few months - until last week. Now he is waking up for feeds every 2-3 hours during the night and the intervals are similar during the day. I was wondering if he is displaying signs of needing weaning - I was hanging on till 26 weeks but thinking about doing it earlier now - or should I just introduce a regular bottle of formula in the evening?
