DS is nearly three and i started potty training on Monday so we are on day five. The beginning of the week he was really into big boy pants and sticker reward chart etc and was trying to pee and poo on potty it seems to have got steadily worse through the week. Yesterday we were at the park and I asked all morning if he needed to go and then after about 2 hours he did a poo in his pants, this morning off we go again and I asked all morning again and then he did another poo in his pants so i explained again how this isn't right etc and he agreed, we get home and this afternoon he has just done another poo in his pants without even asking me to go to the potty, just told me after he had done it. I asked why and he said that he went behind the tree in the garden to do a poo in his big boy pants so I couldn't catch him. What am I doing wrong here and what can I do to make it go better. It's so demoralising, feel like i've spent the entire week encouraging with smarties, stickers, encouragement and he doesn't even try. Anyone have any advice on what to do next? I just put his sticker chart in the bin as told him it was pointless having it out as we never get to stick any stickers on it, this was probably wrong thing to do but so annoyed by that last poo
