Hi JC.
I am a licensed daycare provider. From past experience with having older children during the summer months has been a problem for me, just because the older child is terrible bored because there is noone his age to play with. I would highly recommend to your friend to enroll her child into a summer camp program. They are several offered all over and may have one that he is interested in, say soccer, baseball, etc. Or she can check out the park district programs where she lives or works near. They would have children his own age to socialize with and to be honest the cost to the park distict would be cheaper than paying for a sitter. Good Luck! D.
