I have kids, 3 of them, did not want any. It gets better! It’s normal to not fall instantly in love with them, even for the mother. It’s a new person in your life and require that you adapt and change a lot of things.
It’s not clear from your post what is exactly going on with your wife but postpartum syndrome is a reel thing and may be affecting her.
If you need help reach out to family and friends if that’s possible. Depending on where you are in the world you may be able to find local support for new families, or even dad support groups.
I did not really want a kid but got one, the second one was wanted, the third one a surprise.
I am lucky to be in a good place in life and with a partner that is a great mother and we are a good team all around in regards to raising a family. Our kids get a lot of love from both of us and I like to think we provide them with an environment in which they can thrive.
But let’s be frank, raising kids is rewarding but still can be hard even when your situation is good. It takes a massive amount of time, energy and money. Having childs is often portrayed as a somewhat easy heavenly thing, which is not true.
I can only imagine the amount of work a disabled kid requires and to be honest I don’t know if I could make it. You have my respect for that.
