Why do I keep reading that regent is overkill for most kids? I know it is a big seat but isn't just as safe as other seats? I just bought one a couple of months ago because my ds would not stay still in his booster. We are trying the booster thing again with him and so far he is sitting still and behaving. If he shows he can sit properly in a booster over a peroid of time then I was going to put my dd in the regent. I keep reading it is "overkill" and now I am worried it will not be OK to use for my dd. My dd will be 3 the end of Dec and weighs 32lbs. She is in a marathin right now but I planned to move the marathon and parkway in my husbands car and use the regent for dd and a new booster for my ds. Should I get another carseat for my dd for my car instead of using the regent? Opinions would be greatly appreciated.
