If you have a child who is ready to move into a car seat, it's important that you check the harness straps. You should loosen them so they are a little bit easier to fit on your child's body.
If they're too tight, it could be dangerous in a crash because it would allow them to slide out of the seat and possibly fall out of the vehicle. This could cause serious injury to your baby.
To loosen the straps, push down on the release lever on the back of the seat. This releases the tension on the straps and allows you to pull them down.
You may need to do this multiple times until you're satisfied that the harness is at the correct level for your child. You can also do a pinch test on the straps to make sure they are tight enough for your child's safety.
To loosen car seat straps, first ensure that you have the chest clip and crotch buckle securely in place. This is especially important if your baby hasn't been in the car seat very long.
Once you're sure the crotch buckle and chest clip are secure, you can loosen the harness straps by pushing down on the release button of the harness. Once you've done this, you can then tug on both of the harness straps and see if they are loosened enough for your child.
