Hi,

OK, so things are going the right way. You would expect a baby to lose around 10% of her birthweight and to regain it by 2 weeks. Not quite - but close, especially considering other mitigating factors, such as her prematurity (yes she was a bit!) and her recent illness. Then you would expect her to gain between 150g per week and 250g per week. 250 is the high end of things.
Motilium has it's place, but it's overused and over prescribed. Your milk supply is low (ish) b/c your baby is not feeding properly. If you expressed, your supply would increase (quickly) and a good feed of breastmilk, given in a small cup, ie a medicine cup would make her much more wakeful and "organised" in her feeding. The first signs you will notice are more poos and a more demanding baby. Get onto your local ABA group first thing in the morning and hire an electric breastpump. It will be the best investment you make - join ABA as well.
I will suss out an LC near you.
