My DS is 30 months old (dx'ed at 19 mo with moderate CP, non-verbal and gross motor delay). He's become really picky with his food, he can finger-feed or use a spoon with assistance, but recently has whined and cried whenever we sit him down to eat. Is this a phase? He's been a bit out of sorts since his MMR booster last week, and has had a cold, but has been weird about food for about 2 months.
