My son is three years old and has been fully potty trained since May. But for the past two weeks he has been wetting himself, the bed, the couch. This seems to only happen at home, which is concerning. At school I understand when his friends go to the toilet, he will go too. But even though I sent him to toilet twice before nap time, he still we the bed.

He is a difficult child, strong willed and stubborn. I don't mind this as he is very independent and confident. He has also become very mommy-obsessed. I am sure he is feeling insecure about something, but I can't ignore his behavior just because he is insecure. I have told him that if he wets the bed again, he will not be allowed to go to swimming lessons. I tell him calmly and nicely, but firm. I have put diapers on at bed time, but it seems as though he thinks this is the easy way out.

Bed time has become a nightmare, as he wants me to carry him, cuddle him, tickle his back, sleep by him and stay in the room with him, which he has never needed before. I tell him 1 minute of back tickle, but he screams blue murder when I stop. This is difficult as I want him to feel secure, but at the same time I don't want to promote this needy behavior. I am always affectionate with him, we spend a lot of time together. Weekends he has nap time in bed with me (although I might have to reconsider seeing as though he wet my bed), we have bath night three times a week, he helps me cook and do laundry. He is actively involved in my daily life. So I can't see what the insecurity is caused from. He also can't explain it, being three years old. The bed wetting has to stop, diapers are expensive, and we have used that money for his extracurricular activities at school.

Any advice will be appreciated.
