Regd my one year old child. Please help!

Hello I have a baby boy 1 yr 3 months old. From third month he had problem of reflux so after feeding he vomitted for 6 to 7 times a day. I consulted a child specialist for this. He evaluated all condition did sonography of abdomen and x rays also . He told everything is normal.s since the child is gaining weight also so nothing to worry. Now today after 1yr and 3 months he is having eating problem for the past 15 days he is not eating properly. He becomes uneasy and restless and starts crying as we feed him. He does not gulp food . Again we showed to dr x ray and sonography is normal . No problem medically. He has lost weight also Don't know the reason why he is not gulping food. Please help thanks
