U.M.
Hi,
My son is 13months and he gets sick every 15 days or so. Mostly what other parents have mentioned are great. Couple of other things are run your shower really hot and sit in the bathroom with your daughter to losen up her stuffy nose and her chest. I also rub Vics Vapor Rub on my son's chest (the one for 3 months and over) and make sure it's covered with his shirt. I also use a pillow for his head so he can breath little better. If he has temp I will give him Motrin which will help him fall asleep. I stay away from milk since it was cause him to throw everything up. A nurse also told me that I can pump his nose (the pumper they give you at the hospital when they are first born) which helps alot also. She said I can put it far back as it will go (apparently it will not hurt them) which sometimes will pick up that mucas that is stuck in his throat. I give him a bath, clean his nose and put him to sleep. If it's really bad, I will bring his carseat, sit it so it will sit against the crib or you can put it in the crib and have her fall asleep like that. It will help her breath better since she is elivated. This actually helped me one time when he couldn't breath.
Good Luck!
