I’d never thought about this before:
Here’s something to consider: Not everyone is comfortable with the abundance of noise, speech, color, smell, touch — especially touch — involved with small children. They’re in your lap, your arms, they’re tugging your hands, your shirt, your hair. Again, this affects men and women, introverts especially, older more than younger, and leads both men and women to withdraw (though women still tend to be the parent in the thick of it).
