echt, of course you don't use it when writing. Writing should be more formal.
I use both kids and children. I've been in SW meetings and kids has been used, by Managers/Headteachers etc.
"I’m sure a teacher of mine said kids were baby goats"
Yes they are. We have lots of words in the English language that means more than one thing, some have different spellings, others haven't.
Echt, the issue with children parroting Parents is that sometimes Parents are wrong. It would be better to explain why some people use kids, but they don't like it, rather than say it is wrong. If you correct someone then you assume that you are right.
I'm often surprised about the lack of knowledge on here and across the Baby name threads. We're posters declare legitimate spellings and non traditional English names as made up. If you can come on MN, then you can Google, so they need to use the Internet to educate themselves and avoid passing their ignorance on to their children.
But this is a bullshit thread and not real.
OP, you can't kid a kidder
