DY -“I’m not sure why you think that wouldn’t be effective. If something will be needed when you leave the vehicle, you won’t forget it.”
Some people are out of it, some are very tired. This can tribute for s/o to forget a kid even when you won’t forget the purse, especially if the kid is sleeping!
Also, you have one purse, but you can have more than one kid in car seats!
Nothing is foolproof, but products like BabyAlert.info are much better than things like purses!
