id say she is what she is.... she is 1.
recommendations are to keep kids rf till they are at LEAST 2 and 30 lbs is that not so?
The study showing 500% safety increased was not conducted on children over 2, as the real life data just isn't there yet. There is no reason to think that the numbers go from 500 to 0 at 24 months.
It's only been in the last six months that the US has produced multiple convertibles capable of getting most kids to the fourth birthday.
In spirt, though, you were right There is never a scenario where a forward facing 1 year old is ok.
