Maybe you get hit with that sinking feeling you forgot something. Car keys: check. Sunglasses: check. Wallet: check. Baby...Uh oh. Never fear. Now you can get your hands on the Child Minder System, which sounds a keychain alarm every time you move more than ten feet away from your kid's car seat. It attaches to the little buckle on the child restraint system, so you don't end up leaving Junior in the car for hours while you play Bingo or something. You know, I'm sure it happens ALL THE TIME.
I'm scoffing a little here, but maybe there's some good responsible citizens out there who have had this problem. There's certainly a lot of schmucks that have. Now, if you forget your keys and your baby in the car...well, we can't help you there.
