DS is 3. Started this morning, bare bum. Almost half of wees have been successfully in the potty since about mid-morning, a couple have been total fails and the rest are kind of half and halfs - he starts to wee, then stops when we say to wee in the potty and not on the floor, and goes and finishes in the potty. He gets where to go and what to do, and if we see him jiggling we tell him to go, but he will flat out deny he need to go then start peeing on the floor a minute later. I have no idea if this is normal or not, or if we're doing something wrong??
