I have the opposite problem of most parents. I have two small children. My daughter who just turned 5 is 32 lbs and 41 inches tall. My son who will be 4 in 2 months is 38 1/2 inches tall and 32 lbs. I need booster seats for them because I am giving their Roundabouts to there little sisters who are 5 months old.

I was getting ready to buy the Britax Parkway but read another post about the booster not being a good choice for children under 5. Is this true? why not? would my children be safer in the roundabouts and me being 2 new roundabouts for the girls?

Thanks for the insight.
