Booster recomendation needed

[Oceana]

I put this in the community forum earlier... I am geussing it was the wrong board

Life has changed and carpool has as well

I will be driving 4 kids home from school in the afternoons... here is a word problem

I will have my 30ish lb 2 1/2 year old

a 2 year old weighing also about 30 some odd lbs who is slightly taller than the 2 1/2 year old but has low upper body strength

I will also have a 4 year old who is about 44 inches tall and nearly 50lbs

and a 4 1/2 year old who is 44 lbs and 41 inches tall

I have in my van a Britax Decathalon
a built in car seat

Boosters will be easiest for the older 2 and they will be on the 3rd row

I clearly know I want a high back booster...

what would you recommend?

I also worry that putting my nearly 5 year old in a booster in the van will make him unhappy with his 5 pt safeguard in my smaller car we use on weekends... how to deal with that impending drama?

What is the vehicle year, make, model?

Does the 2 y.o. have a diagnosed condition that indicates slow bone growth?

My DD has been switching between harness & booster for quite some time now -- we have no issues because of this because I have shared the crash videos with her showing her the importance of using the booster correctly + I explain that we use the harness when we can because it's safer & I love her so much....

the car is a pontiac montana 2003 it does not have latch in the third row. On the middle row we have a built in and a decathalon (latch installed)

The 2 Yo has apraxia (which includes low body stength especially in the upper body, he weighs the same as the 2 1/2 year old only he is about 4 inches taller)
