My DS is similarly fussy, he will only now eat meat or biscuits... Mmm healthy.
I started hum on pentavite this week, not ideal but better than nothing. I'm luck if, at the moment, he'll eat more than 3 nuggets in any one meal. Depressing for me but Im assuming that he won't starve himself.
I'm hoping it will pass, he used to love veggies but now not at all.
