Hi O.: I am a single mom with a 17mo old little boy. He has been sick one right after the other since he was born. My son went through the same issues. Try and ride it out. If she starts to act bothered, then take the extra step to see the pneumonologist. But when you feed her, make sure that she is not laying flat, sit her up. If she is laying flat then the fluid can sit in her ears and result in an ear infection. I learned this the hard way.. Sometimes it can be a little allergy or even the change in the weather. I would try something other than the Little Colds. It never worked for my son. I would check with your ped to see if you can give her Infants Tylenol Cold or something similar. Since they are so little, it just can't come out when they cough so it goes into their stomach and comes out in their poop. If you have used the saline drops for her nose (which by far is not fun to administer), that should help push everything down and out. How did the expectorant work that your ped described? I wouldn't wait too long especially if her cough isn't getting any better. If she has had a fever too. One thing that you should watch for is RSV. (They should have tested her when you went in). In my journey of multiple ped visits, I have learned to ask as many questions as possible and even request treatment. Even ask them if a nebulizer may help out. It will get better eventually but know that you can never ask too many questions with a newborn. L. Perez
