Query: Baby can't sit upright and the tray is way too high

Like other reviewers, I also thought this high chair -- with the ability to recline, the dishwasher-safe tray, etc. -- would be perfect for my baby boy. It worked well when he was first starting to eat solid foods, but once he was able to sit up on his own and reach for finger foods, we realized three things: (1) the "fully upright" position anything BUT upright (it's ridiculous); (2) the large tray, when attached, is WAY too high for my now-10 month old son (who is extremely tall for his age); and (3) the "dishwasher-safe" tray is too tall to fit in normal-sized dishwashers.My advice? Don't buy this high chair. We are currently instead using his Fisher Price Easy-Care Booster Seat for all meals (which is a wonderful item, by the way). If we buy another high chair, it probably will be a basic wooden one.
