Seperated from 'D'H and about to start potty training. Thing is whilst 'D'H is fine taking DT's out for trips and playing etc when it comes to the nitty gritty of everday stuff he is very lazy. He has them every other weekend and I know he will just leave them in nappies whatever I say. They are 2 and not really talking yet so can't tell him they need the toilet, although they do give signals which I understand. So how do I do this, will it be confusing for them? Will this be a nightmare? Has anyone got experience of this or any tips?
