She was doing great -- and now she's not
What's going on: Most likely, there's been a shake-up in her routine. That could be something big, like a new sibling or a new house, but even a weekend away or a friend's birthday party can trip up a stellar toilet-training toddler. "If things suddenly aren't as predictable for a child, she loses her sense of security -- and will revert back to something that's more comfortable," Stavinoha says. Don't consider this a failure on your part, or your child's. Setbacks are normal.
Don't reinvent the wheel. "If she was going perfectly on her potty chair but a setback occurred soon after the switch to the big toilet, go back to using the little potty. If she responded to two-hour potty reminders, begin setting a timer to remind her to visit the bathroom," says Elizabeth Pantley, author of The No-Cry Potty Training Solution. A new tactic isn't necessary -- and won't give her the familiarity she needs.
Put your kid in charge. When your kid's stressed, it's normal to want to take over and do the worrying for her. But it can help to give her control. Tell her to let you know when she's ready to start again -- it might be sooner than you think.
