Oddly toyed with in the cases of this troper and her brothers. Our parents never spoke in baby talk with the belief that childhood was a waste of time and that the sooner we grew up, the better. (They did a lot more serious things to deprive us of being kids, as well.) My brothers, my half-sister, and yours truly all grew up to be rather youthful
adult children in varying forms. What's more, my brothers and I are
paraphilic infantilists who enjoy being "babied" by our spouses. By the way, I have actual babies of my own. My husband and I are giving them normal babyhoods.
