1.What can I do if my child is too big for the restraint for their age?
The new laws aim to cater for the majority of children, however there is a provision to allow a child who is too tall or heavy for the recommended restraint to use the restraint in the next age category.

Taurean- I know you didn't mean to come across as a know it all. DH have made a decision based on manufacturers recommendations for our car seat and obviously the size and weight that Frazer is. Going from the above quote we aren't doing anything illegal in regards to putting Frazer in the forward-facing position.

Artechim- I'm not sure why you thought you had to post 2 explanations about your decision to change William's seat around. I full understood your reasoning in your first post. Your decision was made in the best interests of you and him, which I believe is the basis of most parenting anyway.
