@jaderbug, exactly. It's not just women who forget, though, and it'd be nice if car seats just came with this. Sleep deprived people can forget a whole slew of things. I'll never understand how someone can forget their child, but I know it happens. A lot of things I'll never understand happen.
Well now that you mention it @nomaci, when you say that some parents need it to remind them the baby is in the car. Since women lose their memory from being pregnant, it can differ from everyone on how much. Maybe a mom came home and got the grocerys and just accidentally forgot and goes get them immediately. And with this device it will help them.
@hiswifetheirmama, exactly. Why should any parent forget their kids. It was just interesting to see this page at crazy new stuff to make parenting "easier".
