Hello! I am having an issue with my 3 and 1/2 year old daughter. She was completely potty trainined until she just started preschool in Sept. First she started by occasionally wetting her pants. Next she started wetting everyday. I was so frustrated that I put her in pullups to give her a break and regroup. Now she won't go to the potty at all. This has been going on for the past month and a half. What can I do? I am using the sticker chart and she is excited about it but she has no stickers so far.
