My kids get a lot more screen time in the summer but not until they have finished a checklist. I've used it for the last 2-3 summers and it works well. It includes 1/2 hour of reading, 1 hour of outside play or creative play during bad weather, acceptable completion of daily chore, cleaning up bedroom and getting oneself ready for the day. Frequently the outside or creative play extend past an hour if they get involved in something with friends. We also do summer swim team, with practices in the evenings since our neighborhood school is year-round. Each of my kids will do one session of sleep-away camp and then a week here and there of other local camps. This year we are traveling more during summer so, sadly, I think it will fly by much too fast.
