Excellent post @CoveredInCobwebs
Also, as a pp said earlier in the thread, there's a bizarre misconception that people who are child free, go out partying til 3am, sleep in til midday, book last minutes trips to Paris or Rome (as they can coz they haven't got kids
) and go backpacking across South America for 3 months (again coz they haven't got kids.)
The reality is that very, very few child free people do all this. I mean they probably do partying and travelling in their 20s/possibly very early 30s, but after that, no. I mean, most people, with children - or without - wouldn't be able to take the time off to do such things, and very likely wouldn't be able to afford it. Also, the people who have children will very often have done all the partying, clubbing, travelling etc before they had children.
Also, the idea that parents never get a lie-in is bizarre too. I mean, obviously when the kids are baby/toddler age, they wake through the night for feeds, and wake at 6 am (for the rest of the day!) But it will be a short period of time that you 'don't get a lie-in.'
My 2 kids now in their 20s - only a year apart in age - stopped waking through the night by about 2 years old. And then started lying in as long as us by about 4 years old. So after 4 years, we got our 'lie-ins' back.
Also, child free people presumably have JOBS. So they will never get a lie-in anyway, except for the weekend, as they will be getting up at 6.30-7am for work!
So to try and peddle this bizarre idea that child free people have this amazing carefree life, whilst parents have nothing but drudgery and grunt work all their life is - as you say - misleading and harmful. Also, as you said, I don't come across this in real life.
Yeah sure, there are very likely SOME parents who regret having their children, but for many, it will be short-lived and will pass after a year or so, or it will just be occasional (when they're having problems with them, like the kids are misbehaving or causing them some kind of bother.)
For the most part, I do not believe - in real life - that many people regret having their children. It's just something that some child free people make up, as it suits their agenda to believe that.
Also, when I see threads about child free vs parenthood, I cringe when I see some posters who have children, saying 'oh I am so JEALOUS of your life and your ability to lie in and just do anything without having to plan ahead.' I'm like WTAF? Does any parent - in real life - actually think this??? I reckon they're just saying it (whether they realise it or not) as a roundabout way of making the child free person feel better, because deep down, there is no WAY they would swap places with the child free person.
