Exactly and well said.
I had 2 best friends have DC, 1 at 18 and 1 at 24 and the latter was more equipped as more life experience but the 18 year old did it to get away from her DM and said to me more than once after having her 2 DC that she'd wished she'd never had them... she also said the reasons why, e.g. she couldn't work easily etc.
My DM was also a single DM herself when younger but with none of the support DM's have now - her DP's didn't help out much at all with us.
I fell pregnant at 17 and 21 - latter was miscarriage and first one was termination but again I think I was too young - I actually spent most of my 20's panicking about becoming pregnant and taking the MAP even if I'd been on the BCP.
In fact when younger I always said and meant it that I was 50/50 having DC and not having them, I'd also not had good examples of relationships but got married at 29 and then divorced a few years later, he wanted DC, I didn't really, well I did, but wasn't sure if I wanted them with my DH, I also had a miscarriage at 32 and was secretly relieved.
I've known 1 friend who has 2 severely autistic DC and her marriage ended over it - she says she loves her DC but says if she'd known about the autism she probably wouldn't have gone ahead with the pregnancies, another has a DC with Down's Syndrome and also a NT DC and says it's hard work with the DS DC. A neighbour and friend has 3 DC under 10 who are all NT but says it's hard work!
I'm now too old to have DC but would maybe adopt or foster if I met the right man.
One close friend with 2 DC who I thought was really happy - 2 NT DC, nice DH etc - said to me one day "it's great having DC, a family etc but you realise from the moment you're pregnant and have DC that you are now responsible for them, it's not like with someone else's child, you can't give them back etc, it can take time to come to the entire realisation of that but when they're babies it brings you back down to earth pretty quickly, the scale of it all, the responsibility!"
I thought the above statement was very frank of her - and I suppose it is true.
