My 8 month old is pretty good at toiletting - but sometimes does a poo inside after his tea (despite me taking him out a few times.)Problem is that he doesn't bark to be let out and I can't keep the kitchen door open in the winter! How long after they eat do they normally need to do a poo? I don't want this to become a habit and I'm not always in the kitchen all the time at this time of night so can't watch him all the time! Thx
