Not that I’m having this issue, but my wife and I are considering a second kid and this is a thought I’ve had.
It’s funny, you think you will run out of love but you won’t.
It is likely you will feel closer to one than the other, people are individuals, even kids, but your wife may be closer to the other, and they also will have each other. Don’t worry just love them.
This is what’s so wild about my relationship with my first. I love her so much it literally pains me. I can’t get enough of the smiles and hugs and laughter.
I can’t imagine it would be different with a second, but eventually they grow up and become their own people.
You don’t get to choose your family and I don’t think it’s always possible to be friends with your parents. (Mostly because I don’t think I’d be friends with my dad outside of our familial relationship).
But I would hate for that to happen with even just one of my children.
You grow more love with every precious moment you share with each child.
