At the beginning my son had trouble swallowing the pills. He was able to do it, but some mornings were a struggle. We found milk was the best to use, maybe because it was thicker than water. And putting the pill in and then taking a big gulp of milk helped. Some mornings he’d have zero problems, some it took the entire glass of milk and so many failed attempts.
Over the years it’s gotten better and for awhile I’d see him swallow the pill without a drink. We switched to Focalin and its a larger pill, so he’s back to swallowing it with milk.
Hang in there!
