We have an '08 Toyota Sienna with three kids (8,6, and 3 yo) with twins on the way. I am planning on having the twins in the 2nd row in infant carriers, and so the other three will have to fit in the 3rd row. DS (8 yo) is currently in a backless Amp, and I have done the 5 pt test on him, so I think he can go without. DD1 is currently in a Frontier SICT harnessed, and that seat is monstrous, so there is NO WAY it is fitting in three 3rd row. Dd2 is in a Britax Pavillion.
So, I need to figure out a seat for DD1. I don't know her exact stats but she is about 40 lb. and about 42 inches tall. Ironically, DD2 is about the same, a couple inches shorter.
I know it's going to be a huge pain for me to buckle and unbuckle kids in the 3rd row, so what seats should I get for DD1 and DD2? DD2 still occasionally falls asleep in her seat, so would a Hbb be sufficient or should I keep her harnessed? DD1 will be 4 soon and am wondering if I should keep her in her current seat or if she could move up to a hbb. She also falls asleep in her seat frequently.
