I hear it’s normal for some moms to not feel an immediate connection with their baby. I would def reach out for some help in case it is postpartum depression. You are not alone, and you are not a bad mom for not feeling instantly connected.
What they said ^^ and also I’ve heard that your second you’re more likely to have PPD so if you had a girl before and it was easier to connect with perhaps it’s not that you have a boy now but that it’s your second child etc? Sending you lots of love and prayers that you get through this. Please reach out to people friends family and even a doctor perhaps!
Sounds like post partum depression to me. You should really reach out and get some help.
