my child is 1 yrs 7 months and she is only 12kg is this normal girl baby

A. It’s not only 12 kg it’s better than the weight gain that your child should be having at this age 12 KG is ideally a good weight gain for a child who is two years old so your child is already maintaining it at a smaller age which means which whatever feeding and food that you are giving to the child currently is working out favourably for your child
