To be honest, I think he'll last a tiny bit longer in his current seat (bebe confort creatis) but he's a very long tall baby and he seems to be straining against the straps to the point where I'm not sure they'll be effective enough.
I don't want to move him up to a bigger car seat yet as I know that the rear facing ones are safer. But at what stage does it become safer for them to move up to the next stage, even if they're not the recommended 9 months? Any thoughts?
