Bonding

My daughter will be 4 weeks on Tuesday. She’s my second child and I just don’t feel like I’m bonding with her like I did with my son. Besides the fact that she is so unhappy all the time. If she’s not eating or sleeping she’s crying. And she won’t nap without being held and I’m getting less and less time with my son. I just feel overwhelmed and exhausted. I don’t know if I’m looking for advice or just people to talk to and make me not feel so alone.
