I have a 2.5 year old DS. I weighed and measured him today and he is 11.8kg and 92 cm - this puts him under the 25th centile for weight and over the 50th for height.
Looking back to last time I weighed and measured him when he was 2 years, he was also 11.8kg and 88cm - I weighed him naked today and possibly weighed him in pyjamas/light clothes last time so he may have gained a very small amount. He is continuing on the same centile for height though of course has dropped on weight.
Is this lack of weight gain normal? He is not a huge eater, fairly fussy (no veg) and rarely asks for food, but seems healthy and active.
