Thank you for all your replies. Today he actually said "I don't like going to torontokids' house, it's boring" (he doesn't know what boring means but it is a word his older brother uses a lot). I just ignored the comment which I think will be more effective in stopping it.

It is hard not to take this one personally. I think because I am new to this and also because my program is very structured but there is a lot of free time built in which I think is good for them and he seems to love it. It makes you question if you're running a good program, are a good provider etc for sure. I have often wondered if I should have more crafts/activities or keep doing what I am doing. I also question if maybe he should be in another daycare since he's older (3.5) and maybe he needs to be with lot's of other kids his age (currently just has my daughter). I selfishly want to keep him though as he is the same age as my daughter and she would have no one to play with then. I think what is tough with home daycare is that you can often have such an age gap between kids or have only one playmate per child. If the two same aged children aren't getting along then they are out of luck.
