Get ready this could be quite a long message!-my 3mnth old is exclusively breast fed and has put on a steady 5-8oz a week since birth. That was until this week. We don't get her weighed every week any more as didn't feel it was an issue but she has started to be REALLY miserable in the day (has never been an overly content baby and has always whinged on and off!!), so mentioned it to the GP who suggested seeing the HV who suggested weighing and hey ho my daughter now weighs 2oz less than she did 3 weeks ago. We are devestated and the knee jerk reaction was to give her formula as presumed she's not getting enough milk. However have not done this so far even tho the GP thought it was a good idea. The thing is, even tho she is grumpy in the day she still sleeps throught he night (12+hrs) and seems healthy otherwise. Is she unhappy cos she's hungry ?? Am really reluctant to give formula-does anyone have any ideas on how to boost milk supply??
