My baby is only 12.5 kg now at 3 year and 4 months. Height is 96 CM. Is the weight is proper for his age or is there any concern? How can I increase his weight in healthy way?

A. hi weight is little bit less. but no need to worry about it much because it is not necessary for a child to reach at ideal weight range. if a child is happy and active ,take food and sleep well, Achieve age appropriate milestones then no need to worry about anything.
