4 Months Old...His First Car Seat

what does every 4 month old need? a car seat! tmz reports:

An employee of the Toys 'R Us in Porter Ranch, Calif., a suburb of Los Angeles, told TMZ that Spears and her assistant were there on January 15 to purchase a car seat and a stroller. The employee told TMZ the manager installed the seat in the assistant's vehicle.

doesnt this seem a little behind the curve? isnt a car seat one of the first things you snag for your kid...so you can get them home from the hospital? $10 says that brittany is the one who sits in it before the kid does.
