My son is almost a year and a half. I'm getting a second car so i'm going to need another car seat. He weighs just shy of 30 pounds. And he is about 31 1/2 inches long. Is the saftey 1st vantage booster car seat okay for him? He is already forward facing but I am confused to whether this is just a booster or if its a car seat and booster in one?
This is what it looks like.
