Ella, 29 months, is very close to the rf height limit on her new generation Britax seats. I thought she was getting close, but I realized tonight she is nearly even with the shell . She needs to turn ff, and I am trying to decide who should get the one usable top tether anchor. We have a 2006 chevy trailblazer and 3 kids. Kaylynn and Deacon ride in the third row, Deacon is in a fr85 installed lbp and Kaylynn in an amp. Ella rides in the 60 side of the 2nd row, where LATCH is available, in an advocate. Deacon is 5yrs and 40lbs (he is not quite ready for a booster), Ella is 2.5 and 29lbs. Who would receive the most benefit from the top tether? I know ideally they would both get to use one, but I have to have the 40 side (the only other LATCH position) open for access to the third row. I have also thought about getting a new seat to rf her longer, but money is super tight right now (but it will be an option is a couple months).
