you had a CS didnt you?? I was told that CS bubs often snort etc as they can have excess mucos still in their system. My DD2 is a day younger than yours and was born via CS she is a huge snorter esp at night. She has to be held to sleep unlike DD1 who would self settle from day one. She has had the odd vomit but never projectile- well not as of yet so i dont know but i'd assume all is ok if she is having wet nappies still.
