My daughter hated the syringe, too. I have found that a dropper works better. I think that the issue is that a syringe shots the medicine into their mouths and that feels scary. When I use a medicine dropper, my daughter (18 mos.) takes it willingly and sucks it right out.
Unfortunately, the steriods usually taste pretty bad, so that may also be a deterrent, and motrin is REALLY hard on the throat (I taste everything my daughter takes, just so I know what she is dealing with. - Just a lick, mind you.)
I always have a cup of water at the ready so that the second my daughter takes the medicine, she can rinse the taste out of her mouth.
