I bought my boy a little toy mower that blows bubbles. he follows me around when I mow and loves it. In like 3 yrs, I won't have to mow my own lawn for like the next 10yrs after that.
Also, now when I am at the inlaws or really anywhere with my kids, you can leave whenevs you want w/o looking like a jackass. Just say something about a tired kid and it's all good. No one wants a kid to explode in front of them.
When they are young, everyone thinks they are cute and wants to watch them for you while you got to Wild Wild Cat games. When they aren't young and cute anymore, they can watch themselves, after mowing the lawn, while you go to Wild Wild Cat games.
