thats why i usually ask dh to fill cars up as i cant leave by babies in the car at all... even getting them into the car when the car is warm i freak at tad.... i usually start the engine turn a/c on go back inside grab the toddler and baby then get in when car is cooling down. So yeah im with everyone leaving a baby in car with window down is not only stupid it is dangerous.... baby can die easily with heat and/or someone could grab the kid and run (i bet that mum didnt think of that one) ..... some women/men dont deserve children when theyre so damn flippen with them
