i feel liek i don't love my son...

I prefer to stay anonymous... what is wrong with me... I don't feel a strong sense of love for my child, unlike other mothers. I really feel just normal, even tending not to love. I've never really liked children. But I am still responsible, I breastfeed, take care of everything that is needed. I just don't love. No one knows this, including my husband. But I think he might have noticed, because he once asked, "Why don't you ever post photos of our child (on socials)? Unlike other mothers. You do like posting (on socials) a lot..." I just gave him a casual answer, I said I didn't want to invite negative comments, but actually, it's because I don't feel it's special. Is it wrong? But I do take care of him.
