Hello! I lurk a lot, but rarely post! I don't have any living children of my own, but I am a nanny for two 6 1/2yr olds. One is very petite and 35-40lbs I would guess. The other is built very big, about 60lbs, maybe more. This twin has autism, and is prone to extremely violent outbursts. I've been in the Mom's car with them before, where he told her to go to the car wash, but we couldn't because the windshield was cracked. He proceeded to un-do his seatbelt, leap forward, and punch her in the head. I had to un-buckle myself and climb in the back to settle him down. I wasn't able to get him buckled back in, I barely got him to even sit.
SO, all that to say, I need 2 backless boosters for them in my car. They will be used extremely rarely. I'm trying to decide between
this one, and
this one. The only difference is the extra arm on the belt path to prevent submarining. I really want this one for the small twin, she is very petite. But I was thinking the regular one might be best for the boy, to allow more thigh room.
Second question is if anyone here knows of anything that can safely be used to keep the seatbelt from being unlocked. I do not want the above scenario to happen when I'm alone in the car with them, unable to do anything until I can pull over. I would also tell Mom about it so she could get one too.
Oh, and they are both boostered in harness-to-booster seats in Mom's car, and backless in Dad's car.
Thank-you!
