Any thoughts on extended rear facing car seats? Want to upgrade for my 2 year old when new baby comes along (so baby can use the Isofix base and 2-3yo has option of rear facing for longer). Have so far narrowed it down to the Besafe Izi plus, Britax Max Way or Axkid Minikid. Does anyone have these? Any issues we should be aware of or things to recommend them?
