Not the thing you want to hear - sure shows parents have no idea what we go through with the kids and the issues the parents created in them. This kind of thinking makes me so mad. I don't do a lot of crafting with the babies anyways. It is not my job to make something for the parent's refrigerator so they can brag about how great their kid is. If they want fingerpainting they can do it themselves.
Not sure what the supply and demand for kids is in your area but this situation is sure not starting out very well. Unreasonable demands, not hearing what you are saying - I assume you have mentioned that child is taking extra time to settle in and get comfortable.
