hello.
i saw bubble gum balls-kids vitamins at vitamin world last time i stopped in. probably would be easy to convince him to chew gum.:p
also- vitamins that you swallow might be a good idea to try.
vitamin world has 30% specials beginning of each month with membership card- and membership is FREE.
ot try wal-mart -they have great prices on vitamins!!!!
good luck.
sincerely-sheila ann anderson
