The kids alternate between wearing swimsuits and wearing nothing. Olive especially. Age 3 - she just wants to constantly put on a swimsuit in case swimming could spontaneously break out. We have the plastic kiddie pool out back, and Marc takes them to the YMCA pool a couple times a week.
Olive even got up one night after she was changed for bed, took off her jammies, put on a swimsuit, and that's how we found her the next morning.
The kids are protected by a layer of dirt, sunscreen and bug spray, and more dirt, at all times. We have a bath every other day or so to re-start the layers. If we didn't do that they'd get rings like a tree.
There's no school so we stopped caring about bedtime. If they want to have a sister sleepover in the basement in their playhouse with blankets, whatever. We can't hear them down there.
I get home from work and change into a skirt and tank top, sit out back with a glass of chardonnay and watch the kids or work in the garage. We get invited to friends houses for dinners and I'm still outside in a skirt and tank top with someone else's chardonay and the only thing that's changed is the yard, and only barely. The TV isn't on as much unless we really need to come in from the heat and relax.
More outside time, less caring about plans, more late meals, more going to visit friends, there's so much it can feel exhausting and we have to remind ourselves we've got three whole months.
