I've read about keeping the baby rear-facing for as long as possible, although most people I know in real life turned their babies around at one year. The carseats I have can be used rear-facing to 30 lbs, which will probably take my son another 6-12 months to reach, but he is tall enough (32 inches) that we are wondering what to do about his legs. We have been having him sit crossed-leg, but his knees rub against the back seat and he seems very uncomfortable. How tall were your children when you turned them forward-facing? Or is the height irrelevant?
