The advantage of a backseat mirror is simple; it is a fantastic way to watch over your baby while driving. When your little bundle is in the rear facing car seat, you really have no idea what is going on back there without a mirror. Nowadays, companies such as Sunshine Kids, Eddie Bauer, Safe Fit, Munchkin, and Fisher-Price all have great designs most are simple to install. Most models work on the mirror-to-mirror method, which simply means a mirror is positioned on your baby and also tilted to where you can see it from your rear view mirror.
Some models are large enough you can see your entire baby while smaller models make you choose an area such as "face" or "belly". Whether you buy cheap or pricey, plan to adjust the mirror every three to four trips. Simply the movement of the car and placing your baby to and from the car seat base will cause the mirror to shift. It does not take much to re-adjust the mirror.
Headrest Car Monitor
To install a back seat mirror, first you will attach the mirror to your back seat. Some models attach under the headrest using Velcro. If your car seat is positioned in the middle, you may want to check the installment guide to make sure it will work in your vehicle, as some middle seats do not have headrests.
Next, enlist a helper or you will spend quite a bit of time adjusting the mirrors in order to see your baby easily. Sit as you normally do while driving and look into your rear view mirror. Have your helper adjust the mirror in the back seat until you can plainly see that sweet little baby face in your rear view mirror.
You are now ready to travel and know what your baby is doing. You will know if baby is happily playing or sneaking in an extra nap.
