I posted another thread a while back about safe travel while visiting family on the mainland. Since I will be flying alone with the kids, I can't carry two car seats for both, so the general consensus of the other thread was to bring a car seat onto the plane for my 1 y/o and to bring an inflatable BubbleBum booster seat for my 5 y/o to use in the car when we get to TX.
So I was shopping for the BubbleBum on Amazon and saw these seatbelt adjusters
and though they looked better than a booster and are MUCH more affordable for me. I was disheartened by the reviews, however. A few say that the product is not safe because the lap belt is pulled up too high by the device since the cross-strap type of seatbelts do not retain their tension. I was wondering if this product would be safe to use if I installed a seatbelt locking clip on the belt while using the seatbelt adjuster. I have the metal locking clip that is commonly used for car seats in vehicles without a L.A.T.C.H. system. The tension adjuster would keep the lap belt firmly down in place over the child's pelvis like the seatbelts in an airplane stay tight.
Would that then be as good an option as using the BubbleBum? I'm no safety expert, but it seems like using the locking clip would be additionally safer since the child could not wiggle around in the car and loosen the lap belt which should be nice and low over the thighs.
So can I/should I use the locking clip with the seatbelt adjuster? And if not, for some reason, can I/should I use the locking clip while using the BubbleBum to keep the lap belt snug and low? Or is there a reason why this is a big no-no?
Mahalo for the help!
