Currently, due to sibling issues (hitting and whatnot distracting the driver), my DD's are on opposite sides of the third row in my Sienna. DD2 is 3.5 and FF in a Radian on the passenger's side (so there is a tether and latch). DD1 is 5.5 and is on the driver's side, seatbelt install in a Nautilus - no tether in that location. The middle seat will have a sibling in it soon.
My question is this:
Is it safer to have DD1 stay in the five point harness without the tether, or would I do better with a HBB since she isn't tethered? If a HBB, is there a good, safe one that is skinnier than the Nautilus? She is definitely mature enough to be in the booster (though maybe less than 5 times a year, she'll fall asleep in her seat). I know the Nautilus can be a HBB, so that is fine too What would be the safest choice?
