Apparently my mother was in a similar frame of mind when pregnant with my eldest sibling and even after giving birth she took a long time to feel like a mother.

Luckily my parents lived in a small close knit community, because on a regular basis she would go to the local shop get her shopping but forget to take pram and baby home with her
The little old ladies would keep watch and also take bets on how long she'd take to realise her mistake. it was the running joke but they also understood that as a first time mum she was taking time to adapt. Today I think people would be horrified and label her a bad parent but she did adjust and was and still is a great Mum

So give yourself a break be honest with your health care team because they have seen it all before and may have some useful tips on helping you connect
