My DD is 2.2 and constantly pulls her arms out of her car seat straps meaning she is only secured in at the waist. No amount of me telling her off makes a difference. I have been researching solutions such as the Houdini Stop strap but think she will easily unclip this herself (on of her favourite things is to unclip clips!) and also read it is illegal to have chest straps in car seats in Europe??!
So found the '5 Point Plus' Anti Escape System 5pointplus.com and wondered if anyone has used this with success. It is still relatively new to the market and not that many reviews.
