Hi M. - sympathies are with you, definitely! No fun when you're sick, too. Well, never fun when our babies are sick, either..
My son had a lot of respiratory issues as an infant - colds, etc. I hated to medicate him, but did when necessary, I think starting at 6 months. If your daughter is very congested in her chest, one thing my pedi had me do was to clap him on his chest to start to break up the gunk. It startled him for sure, but I would just cup my hand and kind "thump" on his chest semi-hard. It did help break it up, allowing me to then suction the heck out his nose.
While you're waiting for a call from pedi, go ahead and call your local pharmacy and ask what they think is best to give a baby for a cold. As another mama said, Triaminic works awesome and is usually my brand of choice. But a pharmacist might make you feel better about giving her something.
And don't forget to take care of you!!
Good luck - S.
