My daughter is about 4.5. She is very smart and has never had any developmental issues to my knowledge. The problem is that lately she has been drinking things she shouldn't. Her list consists of nail polish remover, bleach, and as of tonight I found out that she urinated on a cup and was drinking it. I'm not sure what to do. I'm stressed out. She knows it's wrong but she keeps finding things to drink behind my back. I'm scared and need to know if anyone else has experienced this or what I should do.
