Question: What are the most important things to consider when choosing an infant car seat?Selecting a seat that fits your child and your model car is critical to the safety of your infant. Certain car seats will work better or worse in different model cars (for instance, the space between the front and rear seat of your car may be too small to allow the brand you like to properly recline). You can save yourself time and aggravation down the road by asking the manager at the store you plan to buy a car seat from if you can test-drive the display model of the brand that you're interested in. (Most stores have a display model for each of the car seats they sell.) Be sure to ask to see the directions on how to install the seat. While it's nice to find a car seat with a pretty pattern or fabric, ultimately the most important thing is that the car seat fits properly to safely transport your infant.
Question: What's the difference between a convertible seat and an infant seat? Which one will protect my infant best?Convertible seats are designed to grow with your child, meaning that they can be used in the rear-facing position until your infant is 1 year old and 20 to 22 pounds. A few convertible seats will accommodate a 30 to 35 pound child in the rear-facing position. When your child turns a year and reaches the maximum allowable weight, you can turn the seat into a forward-facing position. Infant seats, on the other hand, are intended to be used only in the rear-facing position and up until your baby is 1 year old and 20 pounds. So once your baby reaches both of these milestones, you'll need to purchase another seat.
While you may use an infant seat for a shorter amount of time, there are advantages to these seats. The design of an infant car seat is smaller than a convertible, so an infant who is on the lighter side (say 6 or 7 pounds) may be more secure in a smaller seat (whereas an 8- or 9-lb baby would do just fine in a convertible seat.) Unlike convertible seats, many infant seats come with a separate base that allows you to detach the seat. This enables you to transport the baby in his seat instead of having to remove him from the seat every time you take him out of the car. It's also nice to be able to buckle your infant into his seat indoors, rather than have to do it out in the car. Another plus to the infant seat is that if you use two different cars to transport your baby, you only need to purchase a compatible base (rather than another car seat) to install in the second car.
