No I wouldn't either.. Infact I don't use any of those products for personal reasons. I think your body does a fine job on its own in ridding the body of a cold/virus.. Of course I am not stupid if my child isn't getting better I go to the Drs.. But most of the time I let them fight it themselves.
If they feel really lousy we use panadol. for coughs I found a fantastic natural one. It is an exporant so helps the body clear plegm if the child is having trouble. I can't remember off hand if you can use that one for under 2's as I bought it for my 4 yr old.
I hope your DS gets better soon. I hate when little ones get sick.
