I'm switching my girls to NBB from HBB in my husband's 2017 BMW 3-series. My younger daughter is 9 1/2, weighs 65 lbs and is about 51 inches tall. Her preferred seat is a Clek Ozzi (which she uses in my car). She likes the armrests and I like the latch. I ordered one for the BMW, but it sits on top of the belt buckle (which is basically flat with the seat). If you don't latch it, you can scoot it over and it will work with the seatbelt. But because the latch connectors don't move, the booster sticks out from the seat and makes it unusable. Any ideas? We have a Bubblebum but I'm not sure she would want to use that on a regular basis. I've also seen the Harmony Youth Booster and the Cosco mentioned here, but wondered if there were other options. Thanks!
