I bought a Regent for my son because he would not sit back in his booster. He used it for aout 4 -5 months. My son is now riding in booster full time so the Regent is not needed. Well, I bought an extra girly cover for the Regent thinking I would use it for my daughter but... I am buying a Radian and will buy a Recaro ProRide is about 4-5 months as an extra seat. My daughter will be 4 in Dec. Do you think I should hold on to the Regent for my daughter? I am not sure she will need it with the carseats she will have. It is such a great seat to have but alas it is just sitting in the closet. So what is your opinion?
