A 2 year old has to be in a convertible car seat. The requirement for sitting in a booster: at least 4 years of age and weight at least 40 lbs.

Why would you let a 2-year-old sit in a front facing car seat if you can do it otherwise (it's NOT useless)? Rear facing is much safer. Well, I let my first child sit front facing when before she turned 3. So I'm criticizing myself too.
