Question: My son when he was in XXXXXXX had a weight around 5.3 kg for 5 months he was mostly on formula Nan pro 1. When we moved to US we switched to similac and now he is 11 months old and he gained only 1 kg which is 6.3 his current weight. He is having 3 meals oatmeal khichdi etc and close to 16 ounces of milk yet not gaining any weight.
Very concerned about him, please suggest. XXXXXXX doctors tell me that XXXXXXX babies are like that only which I don't agree.

Questions:
1. What was the birth weight?
3.1 kg
2. How is the attaining of developmental milestones?
He is not really attending developmental milestones once we moved from XXXXXXX to US. Mostly less than 5 % on a growth chart
3. Is the stool oily and floats in the pan?
no not that oily kind of normal
4. Is there any colour change in the hair or skin?
no
5. Is there any history of recurrent serious infections?
no
6. How many times does he pass urine per day and is the quantity appropriate?
4 Diapers a day
7. Is there any recurrent diarrhoea or vomiting?
No
8. Does he retch and vomit after each feed?
No

The only time he tend to avoid food and formula is when he has cold and cough which last around 7 days. He got cold and cough almost 3 times in a span of last 6 months.
For that reason I ordered 3 boxes of Nan 2 Pro to validate if its the formula or something else. Also when he is normal he eats 3 meals - The khichi is normally heavy with all the pulses, rice and ghee tadka but not really helping.
