DS1 is going to get a sample of "Building School" next week! He is participating in Camp Invention at his cousins' elementary school. (They will both be there also.) It is 5 days of 9:00-3:30 structured science fun. I am very sure that he will enjoy the content, but I'm not sure how he will react to a full day of "school" with so many kids for 5 days in a row.
This spring we were at "Monday School" (WWHM) from 10:00-2:00, an hour of which was lunch and play time. He has been to scout camp that was all day (and overnight), but it only lasted 3 days. I'm actually very excited for him.
DS2 and I will have Monday through Wednesday together, then on Thursday and Friday he will be at Cub Scout day camp with Dad. I'll be all alone Thursday and Friday!
