Worthless....

Im a new mom. He’s a little over a month. But I feel like he doesn’t know me. He’s with my mom everyday when I go to work, and when I get off work I try and take over but he won’t sleep with me, he won’t calm down for me, nothing. When he gets to my mom he calms down, he’s asleep, he laughs with her, he smiles with her. Yet when I get him, he screams his head off. I feel so worthless, I don’t know what to do or how to feel. I want to cry but I can’t. I don’t know what I’m asking for by posting this. I guess I just need to get it off my chest a little.
