Pulling kids out of school depends SO much on the individual situation. Like
@jrabbit, I wish I had pulled my kids out of school more when they were in K-8. Now that they are in high school, it is my sons themselves who tell me they don't want to miss school. Clubs, Karate, school plays, singing, band, Boys Scouts, and now Science Fairs. Yes, I too struggle with "over-scheduling" but I swear, we don't require them to do any of it. We do ask that if they want to end something, they try to do it at the beginning/end of a school year so that it doesn't break the commitment they made to that organization. I think they feel a bit overwhelmed at times too, but they LOVE all the things they are doing, and don't want to lose any of them. Actually, they have dropped a few things, but only to add others. Over all, their grades are still good, so I guess they know what they are doing, and are getting good experience at time management. LOL.
Of course, some schools do have very strict policies, so you do have to know what the policies are. Also, some kids, even in elementary school, struggle academically or socially, so missing a few days for them is hard, even at that age. But in our case, we did take them out a few times, and it was educational (as well as fun!) and they did do homework on the trip, which is a good lesson too.
Whatever you choose, embrace your choice, and enjoy it. We are all lucky to have such choices to make. You are going to have a great time!
