My son gave in to peer pressure. and was trained fully at 3 1/2
My daughter. .. super stubborn. will go pee on the potty only if you pt her on there and refuses to poop. I've decided to give her a bit more time. It's just very frustrating and it's a battle I won't win yet.

I used some psychology tactics on my baby girl. Essentially, reward/punishment. It works like a charm. If you get the child to the toilet in time, reward them, even if you pushed them.. if they pee on the floor, don't reward them - you could punish by letting the child know they made a mistake - i.e. put a frown on your face, shake you head, etc. Really works like a charm if you can get the reward/punishment right.
