Hi We've been using a Cybex impact shield car seat for our granddaughter for a few months. She's nearly two. The other day we got home, I turned round from the driver seat and she said proudly 'Got out by myself!'. She'd managed to push the impact shield forward, pull the seat belt out of the groove and lift it up. I was horrified, although at least she hadn't done it until we'd stopped (pretty sure anyway)! We had followed the instructions, and there's a picture on the seat, and all looks as it should be. But surely a two year old shouldn't be able to undo it by herself? Has anyone else had a similar experience?
