my baby is preterm n birth weight is 1.8kg naw he is somewhat 6kgs at 4mths is it a proper weight

A. It Is an excellent wait for your child at the age of four months because the birth weight was also okay for a preterm child or child was almost close to 2 KG which is a good weight so as of now also I’m going to the weight is very good more than appropriate so I can just say that your child is growing up in a healthy manner
