Thanks for replying. LO is well within the weight limit for group 0 and there is about an inch of space above his head, so is ok for a few weeks at least! Legs are hanging over and half way up the seat though! I will look at the seat you mention. The one I have just got is isofix and reading articles on the internet that may make impact on neck worse in a forward facing seat in an accident (I really have no idea just quoting things i've read!!) The thing that really confuses me is that by looking on the internet the rear facing group 1 seats are made by all the top car safety brands (maxicosy, recaro, britax, graco etc) and advertised as safer than forward facing but not widely sold in the uk! Can anyone else shed any light on these and why they're not widely used?
