If child is being pulled there is no need for a meeting - using the excuse that obviously any of the rules and methods at your house did not meet with his approval. The payment is due either by EMT or by cheque which can be delivered with the child if he is attending or left in the mailbox if he is not attending for the rest of the month.

Unless supply of kids is minimal for your area once there is an issue like this it is usually best if the family does move on and vows not to repeat their mistakes with the next provider.

It somewhat sounds like the child is not ready for group care. I rarely take on a child over age 2 as too much damage has been done by that point that can not be undone easily. Better that they get a nanny and you get a toddler you can mold into the group.
