The only Dad bod I find attractive is my DH's.
I totally disagree that everyone who has a child does it for their benefit. I think a lot of people are projecting their feelings on others. Like me, some people have a child that is the best thing that ever happened to them, but it wasn't their plan. The night before I had my son I cried to my Mom worrying that I would be the worst Mom ever. I was terrified, when I was admitted into the hospital. After he was born, I was miraculously a totally different person. In a 24 hour period I changed from being all about me to being all about him.
OP, I'm sorry that I contributed to taking this thread totally off the rails. One poster hit a nerve. She couldn't be more wrong about many parents.
Once again, I will reiterate that I think the decision for anyone to have children is their decision alone. I would never try to press anyone to have kids, including my own son. It's a very personal decision that's none of my business.
