Ds is almost three weeks old. He lost 14% of his birthweight so we were put on a feeding plan (bf plus expressing and two top up bottles of ebm or formula). Initially it seemed to be working and he started to gain weight. He then lost weight again so the plan was amended to three top up bottles of ebm or formula and as much as he'll take in a bottle each time (some of his top ups are ebm but some have to be formula because I can't express enough for the three top ups). Despite bf on demand and having three 90ml bottles a day he's still losing weight or staying the same. What are other people's experiences of weight loss? How long did it take until your babies were back at their birthweight?
