6 month anxiety

Amanda
My daughter is 6 almost 7 months. Ever since she has been born I get super nervous about leaving her. I work from home so she is always with me. I have only left her maybe 3-4 times with my mom and 1 time with my mil, and every time I leave I can't help but think the worst. Is she alive, is she getting beaten or sexually assaulted even though NO ONE would do that to her and I know that but can't help but think it. Now that's she's almost 7 months I thought it would get better but it's not. My husband and I recently left her with my parents to celebrate our anniversary and the whole time I'm thinking these things. I trust my parents more than anything and my mom and I are like best friends. Is this some sort of postpartum anxiety or something?
