8months baby is 7.3kgs her birthwt is 3.3kgs .is this normal wt for her??

A. Maam if I look at the birth rate and the current rate your child is about 400 g behind the expected weight it should be somewhere around 7.7 kg 7.8 kg but that’s okay sometimes kids do not accept this kind of weight gain as expected so you can include more of protein so the weight increases over the period
