Baby Alert Child Minder Remembers Your Kids When You ForgetS

It's better to be safe than sorry: Baby Alert's Child Minder system (baby not included) replaces the generic strap on your kid's car seat, causing a keychain alarm to sound every time you move more than ten feet from the buckled fastener that ties your tot down. $64.95 for peace of mind.
