This summer I am taking one sa just for the summer, he is 6. He is the sibling of one of my other dck which is the main reason I agreed. I have watched him a few times before and he is a really well behaved kid. He will also keep my dd (4.5 yo) company to play with during nap time...I agree with the others tho, if you have all little ones and this child will really disrupt your routine, I wouldnt do it.
