DS1 is 3y5m and is in RF Two Way Elite. DS2 is nearly 17mo and is still in my Britax SHR first stage seat.
I intended on keeping DS1 RF until he was four. But, DS2 is going to grow out of his seat before then. The reviews for the TWE turned forward facing are just mediocre, it's much safer as a RF seat. So, should I buy a good next stage FF seat for DS1 and move DS2 into the TWE? (I don't like the TWE AT ALL as the straps drive me barmy but it's a good erf seat so I'd like to keep using it). DS1 will be in his next stage seat for a good few years so I want it to be the safest I can get, which the TWE forward facing isn't.
TIA for your help
