First of all hugs to you. And remember you have done nothing wrong. Thankfully you have emails to mom regarding sons bad behavior so that shows his history Of poor behavior and moms responses of nothing more than 'I'll talk to him later'. Also good that his school teacher has similar complaints. I once looked after a child like this whom had to physically remove from play areas to prevent her from injuring herself or others. She would purposefully hurt herself and tell her parents I did it.......anyhow, they as well thought they should seek legal counsel, never did, but I know it's not pleasant or easy waiting on them.

I agree that you don't need a lawyer at this point. If it makes you feel better, go ahead and speak with one. Keep your documentation on hand invade you need it. Other daycare parents dont need to know what's going on right now, you can tell them it wasn't working out with little boy and he's no longer attendng day care with you. As hard as it is, try to remain calm and remember you have done nothing wrong at all. I would not contact these parents at the moment either. Let them be until they contact you. Also I would not be returning their deposit as they took heir son out of care. I wish you all the best and I hope they give up this ridiculousness and begin taking an active role in their sons discipline.
