Interesting post... could it be that the OP does too much with her kids? That they cannot figure out how to entertain themselves?
I hardly spend any money on my kids in the summer. I work part-time and they are on their own while I'm at work. They ride their bikes everywhere and pack a snack in their bag. I don't ever give them cash as everything is either prepaid or free. They have a waterpark pass, a bowling card (2 games per day including shoes), a YMCA membership, a library card, and are in a youth golf league.
I've NEVER heard them say they are bored or there is nothing to do.
I was thinking that the OP's kids complain they are bored because the OP is so good about finding fun things for them to do! Not a criticism but maybe its time the kids were expected to keep themselves occupied and like others have said, had an entertainment budget and when its gone, its gone.
) so they know the limit.
. Learn a new skill together. This summer we cut out all convergence foods. We tried so many new recipes and learn to bake pound cakes. We limit TV, but bedtimes go out the window, we allow a bit more wii and spend more time together. We spend a ton of time at the pool, hit up the local parks, and only do one or two regular movies. We do the free or 1.00 kid movies a few times and red box sometimes. We do have the free bowling, but maybe go 4 or 5 times a Summer. We love Summer. If money is the biggest issue, maybe let them use your budget to plan what they want to do most. I would have the conversation about a month before school is out and set your guild-lines and be firm in them!
