Does your child do fine on the potty chair, but when you move to the toilet, it's panic time? One mom discovered her little boy preferred facing backward. He could put his hands on the tank for stability. Facing backwards helped her child and could help yours.
When all else fails, hang out with other moms and potty-trained kids. Often seeing another "baby" actually using the dread potty spurs a reluctant toilet training into gear. Seeing other kids the same age or or younger going to the toilet can encourage the most reluctant child to rethink their potty resistance.
Good luck, parents! What tried and true trick worked for you?
