I act nervous around babies (please read if youre a parent or something)?

I always worried I would scare them or somethin. Cause one time at a store some baby started cryin when he seen me smiling at him and my mom teased me like "Oh you scared him" and I thought maybe I better be careful around them but once I had my own kid it completely ceased to bother me. I couldn't scare her if I tried, she thought everything I done was hilarious. Now I don't feel nervous around babies no more. Once you have your own kids you get better with other people's kids.
