DH and I had to refrain from poo convos at dinner LOL... Gawd knows what we talked about before DD
Runny poos very normal for teething mate. My DD was (still is) the other way though, she gets really constipated when teething. Brown sugar in the milk works wonders for constipation. Not sure there is much you can do about runny ones, sorry! I got my fair share of those nappies when I was breast feeding her.
