Still feel disconnected to baby

My son is going to be six months at the end of this month and I still don’t feel that strong motherly connection with him. I keep telling myself that it’ll come. Does anyone still feel this way? I feel like he doesn’t need me as much as my daughter did. He doesn’t get sad when I leave. He’s kind of neutral when he sees me.

Sometimes I feel terrible about it but then other times I’m like I want to stay at work a little longer, I don’t really want to hold him, I’m not as quick to tend to his cries. I don’t get why I feel this way because he is a way easier baby than my first. He’s usually pretty happy and doesn’t cry for no reason.
