Tell them to fill their mouth with a drink (soda etc.) Then tell them to put in a pill and then gulp it down. This won the war for me.
I have allergies and needed to take Zirtech. I had no idea how to take a pill and so my mom and I tried many methods. I can take pills now and my doc doesnt think i'm a baby anymore! hope you like my instructable!
