I get anxious for my husband’s newborn shift

Looking for some advice for what I feel is a very unique worry of mine recently.

I’m about 2 weeks pp and get the sundown scaries like a lot of new moms, only it has nothing to do with myself. My husband and I split the night into 6-hour shifts and I get anxious for HIS to start.

He had one really rough night where LO couldn’t be soothed for hours, and ever since I’ve been worried that he secretly hates being a dad because I came down and found him in tears after 4 hours of struggling. Now I get horrible anxiety leading up to his shift, and my stomach drops whenever I hear her cry with him.

He constantly assures me that he loves being a dad, but it’s like my brain is convincing me that he secretly resents me and the baby. Have any other moms experienced this odd obsession?
