As long as it's the right family and fit, I love my drop ins! I have two currently that come about 1x a month each, and I charge $40.00 a day. They are both older but my eldest son gets so excited when one of their days comes around. He especially asks after one boy - they are best friends. Sometimes they just come for the morning, and sometimes we make a day of it. They are really great, chilled out, self-reliant kids and come from fantastic, involved families though, so it gives some variety to our day without too much extra effort on my part. I'd really have to think if I wanted a younger child for drop in...it would have a really easygoing kid or it wouldn't be worth it to me.
