A.W.
Maybe set aside some time for him each day when he can run around naked if that's what he wants!!! Have a countdown or a little race to see how fast he can get his clothes off. Let him know that you are proud of his new skills. And then, after all that fun, lay down the law about keeping clothes and especially diapers on the rest of the time. At his age, he is old enough for a punishment if he does it when it's not allowed. Hopefully, by allowing him the freedom to do it at a certain time, he'll be less excited about doing it at bedtime!!!!!!!!!
