Agreed with all the others. You might also want to consider if this child would be a fit for you part time. I actually did not renew a contract for this exact reason. DCM "told" me that this was how it was going to be now (moving from part time to casual drop in), but she didn't ask me anything about it before "telling" me this. I DO have drop ins, but they need to be over 2.5 years old, fully potty trained, and verbal. Those are strict because I don't want to transition kids again and again and again. I want them old enough to appreciate some socialization, and manage their own business, and then they can join us in our fun.

This kid had none of that and the worst separation anxiety I have ever seen. I pretty much had to increase the days when he was part time or I would have had to tell him goodbye much earlier. Your dcg might really have trouble with the sporadic casual schedule resulting in much more work for you. Take it into consideration, and charge accordingly for how much that trouble is going to cost you. But yes, please set boundaries before any of this care takes place.
