Hi there,
I believe it is absolutely normal. When I was about 16 my mother had my last baby sister, and I had to take her home and care for her temporarily. Being 16 I didnt have much experience with newborns so my aunts came to my rescue. When I changed my sisters 1st diaper I saw the same discharge with mucus you described. My aunts assured me that, that is normal. Then when I had my 1st and only daughter at age 25 I noticed my daughter had blood and mucus. My mother told me not to worry. At our 1st doctor appointment with her, I asked the pediatrician and she said that is normal and will definitely go away, and she went on to describe it as sort of a " mini-period" my daughter is having. It didnt last long at all. I hope this helps. It didnt seem to hurt my daughter, and I was extra careful during those diaper changes.
