OI, booster laws, and an online friend


New member
I have an online friend whose daughter is 9 years 8mos old. She weighs 36lbs and is 3ft 8" tall (so 44"). She is still riding in a 5pt harness at this point, but she is beginning to protest riding in a "baby seat", concerned kids at school and whatnot will make fun of her for that as well.

She also has a form of dwarfism called Russell-Silver Syndrome, which is a form of primordial dwarfism, but these kids are nowhere near as tiny as those with "classic" primordial dwarfism (namely, Kennadie, for example).

She lives in a 40lbs minimum for a booster seat state, and she doesn't think her daughter will gain 4lbs any time in the near future.

Any advice?

My thought is just to go ahead and use a booster (a HBTurbo, a PW, a Vivo, perhaps even a Monterrey? or does the Monterrey have a 40lbs min?), because no police officer is going to pull a scale out of his pocket and weigh an almost 10 year old.



What state is she in? Most states have an age component as well as a height and/or weight component to their child restraint laws. In Michigan, for instance, a child must be in a restraint until 4'9" or 8YO - so at age 8, they can legally stop using a booster even if they're only 3'6".

Personally, I'd be comfortable putting her in a booster provided it fits her well and she can sit properly.

I'm not sure on what state...but I forgot the "OR" part of the laws that usually exists. I'll have her check on that!

I'm reasonably certain that she could handle it (maturity-wise), but question the fit....although my 5 y/o that is 43" fits well in a Monarch and a PW, and she's right at 40lbs.

My DD's have both fit in the Turbobooster and the old Parkway very well at less than 44" and 35-40lbs.

I might continue to encourage her to stay harnessed, with a bigger-kid looking seat like the Nautilus, but suspect a booster would offer very good protection. If I didn't think it would offer good protection, then I would look at it as a medical condition, and explain it like, say, a wheelchair- a person who needs a wheelchair needs a wheelchair, even if the other kids tease them about it (which they should not!); a 9 year old can't just start dragging herself to school on her elbows to avoid her wheelchair, neither can a person be inadequately restrained in a vehicle, y'know?
