Britax has long been a leader in providing booster seats for children. The benefits of the Britax booster seats is the positioning of the lap and shoulder belts to fit correctly on the child's hip and shoulder.
Car booster seats have been regulated for quite some time. If you have a hand me down booster seat for your child it would be best to throw it out and purchase one that was manufactured by the current standards for safety.
There was no information that could be found regarding children's car recalls. However, there have been several car seat recalls including some Britax seats and Graco seats.
The Britax Decathlon convertible car seat is a popular and safe choice for car seats. It features a 5 point harness, with 3 buckles and 4 harness heights, and claims to have tangle free straps.
Some of the safest car seat brands are Koler, Graco, Britax and there are some other brands that are available for consumers to purchase as safe car seats.
Some safe alternative installation methods for booster seats without a latch system include using the seat belt to secure the booster seat, ensuring a tight fit, and checking for proper positioning and alignment.
There are many different brands of infant car seats available. Some examples of these infant car seat brands on the market include Britax USA and Graco SnugRide.
Integrated child booster seats are available on some cars and buses. These usually include five-point harness seat belts. Children who are required by your state's law to use a car seat or booster seat should use the integrated seats when available.
My understanding is that it's related to how the shoulder strap sits on the child and it may vary from vehicle to vehicle. The high back boosters generally have a strap holder that keeps the strap low enough to not cross the neck. There's some great general booster guidelines here http://www.safekids.org/safety-basics/big-kids/on-the-way/booster-seat-and-seat-belts.html
Baby car seats can be purchased through many retailers. Some popular retailers include Amazon, Walmart, Target, Babies R Us, Britax USA and JC Penney. There are various other retailers that sell baby car seats and there are many types so one should do research to find the best fit.
Convertible baby car seats at Toys R Us run from $59.99 for the Evenflow Tribute Model 3811985 to $379.99 for the Peg Perego Model 350BL13. The best selling on their website is the Britax Marathon Model 70 G3 selling $289.99 but currently on sale for $219.99.
It is a common misconception that booster and child seats need to be professionally installed in a car in order for them to be safe to use. In actual fact, car manufacturers and the manufacturers of child seats try to make them as easy to install as is possible to reduce the hassle of have to move or replace the seat.
As long as your baby can sit up on her own for long enough to eat, without toppling or falling forward, it is safe to put her in a booster seat. Make sure the seat has some way to secure her so she doesn't fall out.
