My 4th son just turned 5 months old today. He has been battling RSV for almost one month now. Last week he was prescribed a liquid oral steroid and I was nervous because during this time I had to resort to suppositories for Tylenol for his fevers because he would gag and throw up the liquid Tylenol EVERY TIME!! So...being nervous about the oral steroid that he desperately needed to take, I discovered that if I held him on my lap horizontally, face up, and head tilted just a tiny bit back toward the ground, I would use a syringe and SLOOOWLY squirt into the back of his cheek (like where wisdom teeth would be if he had them) a tiny, tiny bit at a time. This would take sometimes 5+ minutes to allow for cry time and recovery from the murderous trauma he acted like I was imposing on him with each tiny squirt! :-) The further back I got though, the easier it was for him to swallow. If you can bypass those sensitive taste buds in the front of her mouth, the better chance you will have at getting her to swallow. Getting it in the back of her cheek will be your best bet. The head being tilted back seems to really help too because then you have gravity working with you. Gently blowing on her face will also get her to swallow. She may not like anything you do to help her out, but hang in there. She'll get it no matter how much she fusses. Good luck, take care, and happy mothering! :-)
