My DS1 has just turned 2. We started potty training about three weeks ago and he took to it v well, pretty much dry within days. Poo is another matter. He did have several successful poos in the potty but was a bit distressed ('dirty wee wee')and also had a few poo on the floor accidents. In the last week he has been saving it up and doing it in his night nappy. He's obv a bit constipated and uncomfortable. Even though he says 'i need poo poo' he won't sit on the potty and do it. Shall i just leave it and hope it sorts itself out? Any advice? Thanks.
