We forgot Ironhide!!!

Why is it that the 3 yr old always needs to bring a toy to where ever we are going only to leave it behind and remember 5 minutes down the road?...We face this reality almost every time we venture out somewhere. You think I would have learned by now to either A: not bring the toy or B: make sure we don't forget the toy.  But alas I have not and we inevitably leave the toy behind every time. I'm thinking maybe this will spawn a line of toys with a way to strap to the kids so they are not forgotten. Or maybe this will spawn a generation of mothers who have a better memory. I'm guessing no on the latter. So now the decision do we turn around and go back to retrieve the toy or call and let Auntie know that we forgot him and can she please bring him next time she comes this way. We sent a text, don't worry I wasn't driving.
