Re: Too tall for high back booster?
Were you looking at ones that were just boosters? The Graco and Evenflo highbacks have a headrest that moves up. There is a handle on the back and they move up. I think a lot of people don't realize this. They are pretty tall. The Britax Parkway or the Fisher Price Safe Voyage booster go even taller. The Fisher Price is on sale at albeebaby.com for $30 and I think they have $5 shipping. Oh and Target has an Eddie Bauer highback that adjusts pretty tall.
Here is a list to look at:
Evenflo Big Kid(this one seems a little flimsy and does not have any EPS foam)
Cosco/Eddie Bauer(it's at Target for about $80, I think. Can't think of the name )
Fisher Price Safe Voyage(made by Britax, but discontinued, so cheap)
Let me know if I can be of any more help. I know how confusing they can be.
