Is it normal I don’t want to leave the baby still?

Why do I have such a hard time leaving the baby still?

My husband and I are both teachers. Our baby is 6 months now. I went back to work after 9 weeks home. My mom watches her at our house. We leave around 645 and are home by 315. She goes to bed around 7/730. On the weekends I just want to be with her. All my friends that have kids go out and have their “nights out” but I literally have no interest. I feel like I never see our baby and I want to either be home with her or doing something with her.

I know it’s normal to feel that way at first but is it still 6 months later??
