Wondered if you mummys out there can help... my LO 18 weeks has a awful cold. She wont sleep hardly feeding as she gets so fussy on the breast but i know she is hungry. Her nose is running nonstop and looks so sore. Do you use anything to stoo it trying and getting worse? I looked at vaseline but it says if used for a long time you can get lung problems. I dont want to put anything on which will sting. Alsoshe has bad baopy rash which she never has could this be linked?
