Hi, my dd is 8 weeks old today. When she was born she was on the 50th centile and now she is heading down to the 2nd. She is also putting on weight slower. She has only put on 4oz in 2 weeks since she was last weighed and I have been advised by gp to stop giving her breast milk (which was expressed and bottle fed) and to give her formula now. She is feeding every 3-4 hours and generally will take about 3oz any more and she refuses and is sick. What can I do to help her gain more weight? I'm scared she will eventually start to lose weight as time goes on. What will happen if she does? Would she have to go to hospital?
