We practed with mini M & M 's and tic tacs. For each m & m he swallowed he got to eat three.
Also for a while I cut the pill in half and put it on the edge of straw. Then I fed difficult child a drink and it went right down.
At first I bought the liquid yogurt drinks and sprinkled them into the yougurt. He tasted this and complained alot. Others have tried using ice cream. I've even see the shcool nurse give two kids their medication with icecream--whatever works.
Good luck--
How is he doing with the dexadrine?
