I didn't grow up around babies either. For me, I just avoided pregnancy...but once I got her (only one) she became the center of my attention. I do understand though....babies are scary and they take your mind off what we think is important; Ourselves. It's very hard to give up our freedom and independence. An animal can fill the void, but still be left alone or ignored when other things seem more exciting or important to us. Do you have kids? If not, I'm sure one day you'll learn to love them and make them the center of your universe, we just need to do it when the time is right. Now may not be the time for you....
Good luck
