B.C.
My son had pneumonia when he was about a year old. He had to take his medicine whether he liked it or not. I had a pin down method just like Rachel K mentioned and I'd pry his mouth open (get my finger between his gums - this was easier before he had teeth) and squirt the medicine into his cheek a little at a time. He hated it, but as soon as we finished I'd hug and snuggle him and he'd calm down. It was tough, but we got through it.
