Ds is 6 months old and i think he is teething, he hasn't got any teeth yet but it looks like one is on it's way. He is totally refusing to feed, so far today he has taken 300 mls and point blank refuses to take anymore - is this normal during teething? It's really stressing me out as we are in NZ at the moment and it's so hot, I'm paranoid he is going to get dehydrated - what can I do?
