Hi ladies

I have a 19 month old son, who is 76 cms tall and weighs 8 kg and has weighed 8 kg since he was 12 months old. The paed thinks he may have coeliacs. can someone tell me what the symptoms are please?

He eats really well and has been breastfeed, doesn't drink much cows milk but loves cheese, yoghurt and custard. He is also very active.

thank you for any advice xo
