Previously he was drinking milk from katori spoon, he has suddenly stopped drinking milk. He keeps on holding milk in his mouth and keeps crying. He don't swallow milk since 15 days. Because of that he is loosing weight and passing less urine. Whole day I am running behind to atleast make him eat solid.. please help, his birth weight was 3.5kg. but at 9 months he is still 7.7kg, he lost weight from 8.0 kg to 7.7kg in 15 days..
