Bittersweet

I've never collected, aside from the time I stayed both my mother and it was annoying, but now I have a strong want to just cuddle with my baby. She gets very clingy at night as well and I hate that she has to comfort herself to sleep. Throughout the day I have work and when I'm off we play and hang out but we're not in each other's faces. I offer hugs and kisses all day long but why do I feel so empty and like I haven't done enough with her. I can't co sleep with her. Neither of us will actually go to sleep. And idk wear I should do to help this sadness I'm feeling. Maybe it's because she's growing so fast.
