Ds has had to have some long courses of foul antibiotics (6 week stretches). He also takes 4 different medicines daily (which he takes quite happily) The trouble with brute force, is that it could well end up with him being reluctant to take his daily meds, so would be counter productive. We couldn't hide it in food as he has lots of issues around food, and has a very limited diet, so this would only make it worse.
We used to wrap him in a towel, stroke his throat and do it dribble by dribble into the side of his mouth, with a bribe at the end - a nurse at hospital showed us this way, it isn't quick, but the medicine goes in. He doesn't like it, but we do it in the gentlest way possible, and the consequences of him not taking them would have been worse (he has been hospitalised several times with pneumonia and chest infections caused by aspiration).
Sometimes it is necessary for children to take medicines that they don't like (prednisolone steroids are bloody foul, but very necessary) and in these instances it has to be done, and it isn't very nice, but I wouldn't say that it is 'brute force'.
By the way, weebles, I haven't heard of the Calpol method, I will try that next time!
