A. Your kids should be somewhere around 16 kg minimum in this time also if your kids were pretty mature or something maybe you know by the time of this age maybe 14 to 15 KG is going to be good weight gain but right now kids are maintaining for a two year old child please check with your doctor as to what kind of diet and supplements you need to start with
