My lo is 5.8kg Born on 9 april 16 4.5mth old PD and nurse said her weight gain is not enough. How to make sure her weight is increasing at good rate? Height is normal but weight is increasing at a slower rate. LO is bottle feed so i know how much is her intake. 6oz to 7oz per feed 2hrly feeding STTN. Is it due to my bm or LO nv absorb?
