Has anyone else experienced the baby blues? My daughter is 9 days old and I love her so much and I'm so happy to have her. But I also feel down for some reason and I keep crying without knowing why. I miss old things my husband and I used to do. And I'm tired. My husband tries to help but since I'm breastfeeding, we can't exactly take turns getting up in the night. I just feel sad and I hope I feel normal again soon.
