Have you tried one of those little squirter thingys?
Stand him between your knees, tip his head back, squirt in medicine and pinch his nose. He needs to swallow in order to breathe, yes?
I had one, of my seven, who was greatly opposeed to taking medicines...oh my word, I had to lay him on the couch or floor, pin his legs and arms down with my legs, hold his head with one had and squirt the meds with the other then pinch his nose.
He wasnt crying or fussing...amazing yes? But he would take it if I forced him too. Guess he must have just been accepting the inevitable.
And I always prefaced the ordeal with ...you need to take your medicine in order to get better, and I need to give it to you . It would be easier on both of us if you could just take it.
Have you told doc about this? Doesnt do any good to prescrib a med if the med is not being ingested. Perhaps doc would change to the amoxicillin.
If he refuses his meds, and doc wont change it, then there is going to be some stress on his part and yours. Keep your eye on the goal here. Not everything that is good for us and necessary is going to be fun or without stress.
Your job is to give him the meds,no matter what, so he can recover from the pnuemonia, yes?
Pinching the nose works because they cannot taste it if their nose is pinched shut. If your child is an easy one..then tell him you will pinch his nose so he cannot taste it and have some tasty juice ready to wash down and residual taste.
Do what you need to honey.
Best wishes and God bless
