my daughter is 139 day's old. her birth weight was 1.3 kgs. how much should be her approximate weight by now??

A. If your child has gained about 1500 g in three months then that would be quite an ideal weight gain looking at the birth weight your child is quite a was having a really low weight so even if your child has gained 1 KG in this much of a time then it would be good but 1500 gay
