First Cold

My poor little man. He has his first cold. He started with alot of sneezing Sunday night. Yesterday morning when he got up he was fine, then around 3pm his nose started running, along with ALOT more sneezing, and diarrhea. So, I called the Dr. to get him in, and his appt is at 10am today. He can't breathe very well, and each time he sneezes a snot rocket shoots out and he gags and gags. He's also had increased spit up too. He's back to sleeping in the bassinet tonite so he's closer to me. Mostly b/c I'm scared he'll stop breathing and I won't hear him. I have his head propped up and him laying on his side, but that doesn't reassure me at all. I have the humidifier running and I've given him cold medicine, as well as a warm bath in a steamy bathroom, but I think those things just made his snotty nose worse. His little nose is getting red from all the nasal bulb suctions I've been doing as well as all the tissue wiping. He's so cranky and clingy. I'm wondering if it's his first cold or his teeth, b/c his gums are ALL swollen and white on the bottom and he already has one broken through b/c it's prickley. I don't know if children get symptoms like this while teething or not, but guess I'll find out what the issue is at the Dr. in the morning. Just pray he gets better quickly and without getting much worse, please???
