I'm not sure, Drew is teething too and pooing more than usual and farting loads too. His farts don't smell but his poo's are horrific, even when it is a tiny one it lets off a very nasty smell. Drew normally drinks very watered down orange squash, very watered down apple and blackcurrent and his prescription milk. He's not been eating any diferently but yea they're eggy smells YAK xxxxx
