I think my daughter has mamitis

My daughter is a month and a half old, and my husband went back to work last week. Now that my MIL has gone back home, I can't put my daughter down without her waking up and crying. I want to exercise and clean up around the apartment, but she won't let me 😭. My husband was joking with me saying she may have mamitis, and I'm starting to think that he's right.
