My little girl, 20 months, is still in a newborn car seat because her head's well below the top of it and she's not even 20lbs so well below the maximum weight too. But twice now she's managed to get her arms out of the straps and so her whole upper body's been free so she's turned round to us in the front of the car and obviously this isn't safe. I don't think it's that the straps aren't tight enough there's always going to be some pull in them because the attachment to the seat is below the top of the seat so they come up the back of her then down over her shoulders if you get what I mean and because she's 20 months she pulls to sit forwards in it. She's not even the minimum weight for the next stage. Has this happened to anyone else? I guess we're going to have to move her up now aren't we
