My kid is 11months. His birth weight 2.7kg and now he is weighing 8kgs. He was 7.8kgs 2 months back He looks lean. Is the weight gain normal

A. Childhood should be approximately 9 1/2 kg kilogram as per per general standards if I’m talking if you look at the birthdate of the child this is very good but as per general standards if I look at it it is little less so try and include more of proteins along with the food that you are giving
