I'm going to be exposing my ignorance, now. Please excuse me.
My six year old is 39 pounds (yeah, tiny). I need to measure her height, but her height is closer to normal than her weight is.
She uses a Britax car seat but I've forgotten whether it's the Boulevard or what. I don't think it says the model on the seat, just the brand.
The top of her head is higher than the back of the seat. That's a Big Problem, right? I will look to see if I can raise it any higher but I think the last time I adjusted it, I made it go as high as it could.
I've vaguely heard the 4-years 40-pounds rule for a booster. So if your child is 39 pounds but too tall for her carseat what do you do?
And if the recommendation is to move her to a booster, what do I look for? I think it's got to have a back. Anything else?
