Give him icecream? If he likes cold stuff. I gave my boy lots of ice cream when he kana it last month. Cos he has no appetite. N anything else he craves for. Like sweets or biscuits. Of cos, for icecream i gave him only vanila flavoured ones n sweets i gave those ribenas chewy kind. Gotta find the best out of the worst when im gonna have to give him 'unhealthy' stuff.. But i wld rather he eats junk than eats nth at all..
