If by 'Big Kid' car seat you mean a front facing seat, my pediatrician says it has to do with there size, not there age all the time.
a baby can seat in the fornt of the car at 11!!!!
well it depends on what kind of car it is, the year, model, and how big the space is in the back.
most carseats have a lock base which is "locked" in place and left in the car when you detach the car seat from it's base

The best car seat on the market is a seat that fits the baby you don't want one to small or to big. Another important feature is on that can install easy. A brand that I prefer is Graco Car Seats.
The main difference between a car seat and a booster seat is that a car seat is designed to restrain and protect younger children who are not yet big enough for a seat belt, while a booster seat is meant to position and elevate older children so that the seat belt fits them properly for maximum safety in a vehicle.
It's usually determined by a child's height, not age. Once they pass 4'5" (in my municipality) they no longer have to ride in a car seat.

Laws regarding car seat requirements vary by state or country, but in many places, children are no longer required to be in a car seat once they reach the age of 8 or a height of 4 feet 9 inches. Some jurisdictions may also allow children to transition to a booster seat after a certain age or weight. It's essential to consult local regulations for specific requirements related to car seat use. Always prioritize safety by following the recommended guidelines.
You don't install a newborn car seat. The only thing that you need to do with a newborn car seat is put the car seat in the back of the car and put the seat belts on and lock the seat belts.
