I don’t know about disliking kids but I have noticed a lot less people being pleasant about having them and discouraging others. So many times I see people talking about kids or if they should have them and parents say “don’t!” and discourage. Even when I was first pregnant, mums and dads I worked with or knew were nothing but negative about kids and the experience of parenthood. Only one lady I work with had my mentality of children are a blessing in life and positivity around the whole motherhood thing. To me, kids are a true blessing. I see myself happy in life, even on those tough toddler days. I would never say to a person talking about having kids one day “don’t do it”, “are you crazy?”, “your life will be over” (all things I was told). Just last month I was in a shop and the cashier was talking about my new baby and said she wanted kids, the rude lady behind me said loudly “do yourself a favour and don’t”…. Alright crank, wind your neck in.
I'm not sure this is true. In years gone by children were 'to be seen, not heard' and were not tolerated in many contexts. That's different now! Kids are people and as such have just as much right as anyone else to exist in public spaces. I agree that lots of people without kids dislike that - long haul flights and nice restaurants being examples where people can get quite vocal about it. But that's likely always been the case - you just see it more because of social media. People nowadays are also more comfortable and safely able to say that they don't want kids for whatever reason. And that's ok! Those sentiments existed before it's just that people weren't allowed to express them without fear.
