Toilet training regression with new baby on way?

We went through the exact same thing when my second child was born ! I have to agree with the other psots though for sure, positive re-inforement is the best. What we did during her awake times was set the kitchen timer for 1 hour, and we would tell her to listen for it, and when it rang it meant she had to go potty. After awhile we stopped using the timer and now she is back to going potty on her own. Good Luck : ) !
