consider full time LBB use?
Considering the child is a mature rider and not tiny. I understand that her bones are still (nearly) 6.5, even though she is tall (49.5" and 52 lbs at last check).
My older DD is the same size (maybe a smudge shorter actually) but 15mos older, and all torso. She started using a LBB full time a few months ago when her super long torso outgrew the high backs on our Affix. Younger DD is close to outgrowing them also, and I'm constantly back and forth on buying her a taller HBB. My older DD is my wiggle worm and she actually sits better in her LBB (Diono Santa Fe) than she did in either HBB (Affix or Frontier 85 in booster mode - she still fits in that one and it's in DH car because his seat belt geometry is not kind to LBB).
YDD does sleep in the car more than her sister, typically on the way home of a long drive. But she puts her head back, I can't get her to rest it on the side of the HBB.
