We have a super dinky pool that we haven't used since 2014. I seriously doubted it would entertain the kids for long. But I obviously overestimate their entertainment needs. I filled it up on a particularly hot day and they played in the backyard for three hours. Three hours!! Even Emry got to enjoy some frigid hose water before her nap. And she wasn't too sad about it. :)
I mean, this picture! I just love it.
