Hello doctor my 3 year old son has a behavioral problem, whenever we ask him to wear his pants on his own he acts like he feels like to vomit. He gives up very easily on tasks given to him like colouring etc if he is not able to do it perfectly like an adult does. Also he eats very slowly, burps a lot specially while taking porridge and sometimes vomits his entire feed while eating. He doesn't like to swallow hard nuts and most of the time doesn't finish fruits given to him, eats a little bit and throws the rest. What can we do to improve him, specially his burping problem.
