Jo Frost, "Supernanny from the hit ABC show, just answered Washington Post reader questions on everything from potty-training to discipline. Here is a sample:

Minneapolis, Minn.: Hi Jo -

I have a just-over-three-year-old boy who is not yet potty trained. I have tried everything I have read about in books ('potty prizes', encouragement, positive rewards, special underpants, praise, stickers...) to encourage him to use the potty but he is just not interested! I feel like he is ready and capable of using the potty - and we had a streak over Christmas when he actually was using it, but then stopped. Should we keep trying (and if so, what do we do next?) or should we back off for awhile?

Jo Frost: He's more than capable of being potty trained. However you have played and toyed with the idea and he has half-heartedly done so. You need to make up your mind one way or another (and the answer should be yes). Number one: take note of his fluid intake. 2: take him completely out of diapers, no half-measures. 3: Diapers only at bedtime. 4: you will need to spend a week doing this - stay local, no big trips. You can find a step by step guide in my first Supernanny book...

Arlington, Va.: Hi, Ms. Frost!

We are new parents to a 7-month old, and I am wondering about how best to incorporate a routine into our day. Specifically, our baby isn't a great sleeper and doesn't have set napping times. She'll usually take a 1 to 2 hour nap in the morning, but we have trouble getting her to sleep in the afternoon. And we always get her to sleep by walking her in the stroller, as she will cry if we put her down in her crib. Do you have any tips on starting a baby on a routine?

Jo Frost: She should be taking a midmorning nap and then one straight after lunch. Creating a framework is going to be key for her. She may doze off around 5 for half an hour. Not until her eating schedule is in hand should you implement the sleeping technique. In my new book I detail my "controlled crying" technique. In short - Put the baby in the crib, go out, the baby will cry, you go in and say shh and rub the tummy... repeat, doubling the time in between.
