Tighten the anchor belt attached to the base until the base is snug against the seat. Check the manufacturer’s instructions if you aren’t sure if your car or seat has this option, or how to use it. There may also be a place to feed the car’s seat belt through the base for added security.
Read the instructions to study where you are supposed to put the belt if you aren’t sure. Every vehicle and seat is different, so it’s important to get this right. Not latching the seat belt correctly can increase the risk of the child getting injured in an accident.
Most infant carriers have level indicators. Once yours is in place, read this level to see if the seat is at the correct angle for the babies weight/height/age. Check the manufacturer’s instructions for how to properly read the level if it isn’t clear. Change the base angle if the level is not correct or your child. Usually, this involves turning the base over and rotating a piece. Remember to change the angle later on (or switch to a different seat) if the baby outgrows one setting.
Make sure that the belt is not twisted or bunched up as you pull it through.
Consult your vehicle’s manual if you can’t find an anchor.
A forward-facing car seat with the latch system may also include a tether and/or place to feed the seatbelt through. If so, use these in addition to the latch system to make the seat as secure as possible.
How long to keep your child in a rear facing seat will depend on its height and weight, as well as the manufacturer’s specifications. Experts recommended keeping your baby on a rear facing seat as long as possible. Use one until your child reaches the upper height or weight limit set by the manufacturer. Some car seats are all-in-one, starting out in the rear facing position and converting to forward facing when your child is available. Check the owner’s manual for instructions on how to convert your seat.
Make sure the straps are not twisted. The correct way to tighten the straps will depend on your model of car seat. Most have a place to pull on and latch the strap. Check the manufacturer’s instructions if you aren’t sure. For safety reasons, do not place extra material (such as a blanket) underneath the straps. If you want to cover your child, buckle them in first, then add the cover.
