You are not a crap mum op
because you are meeting the needs of your baby; feeding, interacting with him, changing and bathing him, dressing in warm clean clothes, keeping him safe etc etc. That’s a lot of work, and love is a verb, it’s not just a statement with no actions attached.
Many mothers don’t feel that first rush of love don’t worry. Particularly mothers who feel a bit anxious., stressed, sleep-deprived, or lacking in support.
It’s much easier ime to sit back and relax and really enjoy your baby when you have a partner who really steps up so you can take a break, and also a lot depends on how each individual baby sleeps.
Don’t get stressed about it, it will come, but do speak to your gp or health visitor if you start to feel really detached and think there’s a possibility that you may be developing post-natal depression. One of the symptoms is feeling increasing irritation with your baby. But that’s not unusual when sleep deprived.
Here are the symptoms:

Finally, looking back to when I felt like you, over two decades ago, I felt very constrained in a way, but it was all inside my own head, having read too many parenting books, and I was trying to do everything far too “perfectly” and totally ignored my own needs.
Looking back I should have given myself permission to do a few things “my way” so I could relax a bit more.
I know it depends on the child, but looking back I could have put my babies down a bit more too. And I should have asked for more help when I was struggling.
How much help do you have in rl op? Is the baby’s father stepping up enough?
Are you able to afford a baby-sitter to come and just hold your baby while you get some sleep or you have a relaxing bath or do something else in the house?
Hang in there op. This part is exhausting and many women feel as though they are swimming through treacle.
