You know when you are thinking one thing and then you are about to say something profound like ... squirrel!

Me almost all the time with commenting. Most of the time I'll come back and just realise I forgot to press the reply button (I was probably in the middle of proof reading before sending or something before distraction). Other times I was partway through a sentence and cannot remember where it was going XD

but maybe having children younger teaches things that add to what they need a bit later in life, when they have teenagers?

Seems to stil be pretty calm as far as I can tell from most of the older parents that I know that have teenagers (there's always some). You'll be fine too :)

I would have wanted kids in my twenties, but it wasn't to be.

Yeh sometimes life just doesn't align properly.

But having one is better than none in my opinion

Most definitely if you wanted to have kids, and usually better late than never (there's probably a "within reason" to consider but I think those parameters are individual).
