Without further adieu-
What NOT to do-
Car seat straps should NEVER dangle off the shoulders, and the chest plate should never be below armpit level.
(please don't pay attention to the date stamp, it's totally wrong)
Straps should look like this-
Straps should fit snuggly over the shoulders, with the chest plate aligned at the armpits. You should not be able to fit more then two fingers comfortably under the chest plate, nor should you be able to pinch the straps. If you can pinch them, then they are much to loose.
or
Also, proper strap height-
For forward facing(which is the arrangement I used for these pictures, although the seat is not actually installed) the straps should be AT or ABOVE the shoulders.
For rearfacing(which both of my girls are), the straps should be AT or BELOW the shoulders.
Be blessed ya'll!
