Dt's are 29 months, both tell me when they are going for a poo but it tends to be during or just before rather than getting to a toilet/potty in time. If they wee in the bath they are aware of what they are doing and a little bit proud too. They sometimes hold on to their and crouch down - I think they are going for a wee then but again by the time I get to them it's too late.
Is it worth giving it a go ?
What do I do ?
