my 11mo son is exactly the same, we even end up playing a game where he chucks the tennis ball down from the high chat and i run around finding, good for losing weight bad for the back!
But giving him a sippy cup, spoon etc has been helpful, or some small but not swalloable toy works well.
Hang in there, its hard work but one day they will be eating well on their own...and having had a bratty babe of my own, i realize that not everything is about parenting, some kids are just curious and headstrong and you have to bend to them...just my 2 cents!
