What should I do ???

[5 Little Monkeys]

I would talk to them in a very non confrontational tone and explain that in the best interest of their child, they will either need to be on board with your schedule or they will need to find alternate care, perhaps a nanny. I would explain to them that in daycare, all the children need to adjust to the routine because you are only one adult caring for multiple children and for this to succeed and be safe, a consistent routine is needed. If they don't like this approach that is of course their right and by all means you will not be offended if they decide to go with another provider.

Be firm that these are the 2 choices you can see for them but allow them to make the decision. If they were to honestly think about it, they would see that they are doing their child a disservice by allowing him to call all the shots. Most children thrive in a structured routine or at least with a consistent one. Being in multiple child care, they must understand that allowing all the children to do what they want when they want just isn't possible.
