Beating myself up...

My baby is 6 weeks and this whole mom thing is really rough for me... I feel like I never know what my babies needs, everyone told me “you will learn the different cries and I still think that’s bs. I hear a lot about the bond between a mom and baby and sometimes when she’s happy and smiling at me I think I might feel that but i dont know. I feel like I should know what people mean when they say that. I find that I’m upset and frustrated more then I am happy. Maybe I haven’t bonded with her? Maybe this is normal?Maybe being a mom just isn’t for me? She deserves the best mom in the world and I want to be that for her I just don’t know how...
