Maybe it’s to do with whether or not you like babies in the first place. When I was about 14, I used to take my parents’ friends’ babies out for walks. I couldn’t get enough of them. I adored babies! When my daughters had their babies, I was thrilled and excited.
At the same age, my best friend, on the other hand, did not have any interest at all and when her children started their families, she couldn’t have cared less.
Luckily, once the babies wee born, she was won over and all was well.
Funnily enough, one of my daughters much prefers children to be two or three and isn’t really that interested in the baby stage.
Each to his own!
