Where should my kids sit in my minivan?

The 4 and 7 year old where ever their boosters are and the 13 11 and 9 year old first come first get. I'm not sure if the 9 year old needs a booster i do know many kids are going without booster who are small enough fro them but they are still big 4'8. Mine haven't been in a booster since about 6 years old so that's really your judgement call.
