Is it normal to dislike children?
Mostly.Normal for most people
Yes. Plenty of people don’t enjoy being around children, and that doesn’t make you a bad person or mean you have to want kids of your own.
Some people find kids loud, unpredictable, or exhausting; others just don’t feel much interest in them. You’re allowed to prefer adult company and set reasonable boundaries around babysitting or kid-focused plans.
It’s different to dislike children as a group than to mistreat or demean an individual child. You can be civil and kind without pretending you enjoy being around them.
