Ahhh... cos he's a toddler - and this is what they do? LOL

Seriously, try not to let it bother you, get some multivitamins for him if you are worried about his vitamin intake - but its a phase, and mostly every toddler will go through it at some stage, so just try to relax and ride it out.

I've always found that pretending to steal their food off their plate usually gets them to eat one mouthful though
