The current reccomendations are for children to remain
RF until they reach the weight maximum for
RF in their carseat.
Rear Facing offers unmatched safety to young children. The longer the better. I know many parents who are sad when they are forced to turn their children
forward facing. 12 months and 20 pounds are the minimums...but I'm sure all parents agree on this---our children are worth far more than the minimums.
The highest weight limit for
RF is 35 pounds, the lowest 30.
Your 5th month old will likely slow down in growth as he becomes more mobile. Those first months have a lot of rapid growth.
It's a combination of development---skelatal included, weight, height---and poor
RF choices here in the US that determine when to turn children
FF. It's common in Sweden for children to remain
RF to 4-5 yrs old, and their fatality rate for children in that age group is much lowers than our in car crashes.
