your child is ready to use the toilet, it usually takes about 6 weeks from first introducing the potty to the time she's going on her own and staying dry most of the time.
Even after your child is staying dry during the day, it can be months and even years before your child can make it through the night.
Although potty training is a big milestone -- and one much anticipated by parents! -- you'll want to be sure your toddler is ready. Forcing toilet training on a child who is really resisting can backfire. Instead, try to make potty time fun (read stories, sing songs). Offer nonfood rewards like stickers or trips to the park. And don't make your child stay on the toilet if she doesn't want to.
