DD#1 just turned 5 years old, is 40lbs and 45 inches tall. She will be starting kindergarten in the fall and we need a booster car seat that she can get herself into and out of properly when I drop her off and pick her up at school. She is currently in a Britax Marathon and can completely buckle and unbuckle herself, but obviously cannot pull her straps tight enough to be safe. I was initially thinking about a 5 pt harness booster, but it would be extremely difficult for me to tighten the straps from the driver seat as her booster will have to be on the far passenger side of the middle seat. Should we forgo the 5pt harness and just use the seatbelt that I can easily check that she has latched?
