not bonding?

Anyone having issues bonding with baby? I just feel like every post I see is about how much everyone loves their baby so much and how happy they are and I just don't feel that way. I feel like a bad mom. My husband loves the baby so much and I honestly don't really feel anything towards him. I mean obviously I love him he is my baby but I just don't feel the overwhelming love everyone else seems to have. Luckily my mom is staying with us for a few weeks and she is helping a lot because I feel like I can never get him to calm down. He is constantly wanting to eat and if he's not on my boob he seems to be crying. She can calm him down and get him to sleep but I can't and I just feel like a failure and I don't know what I'm going to do when she leaves :/
