DD1 just turned 3 and we've had her mostly RF unless she's in a secondary car like DH's or my mom's. She doesn't care which way she faces and I think actually it's probably more comfortable for long car rides when she's RFing because she can put her feet up instead of them dangling off the front.

I was thinking we'd get her a new harness to booster when DD2 needs the convertible seat in 6 months or so but DH reminded me that we can just use the other secondary convertible. So we may not flip DD1 until she grows out of the height limit! Who knows.

If you had your kiddo RFing until 3, what made you finally turn them FF? Or have you not yet?
