C just figured out how to get up on all 4s by herself! Proud mama

For those with experience, how long did it take your LO to crawl after they figured out how to get up on their hands and knees? Just wondering how much peace I have left before the crazy begins!
And sorry I've been MIA! Things have been nuts ever since Thanksgiving and I'm ready to let things settle back down in the new year...and get my bump on
Re: PWHEW crawling
my read shelf:
All of this, dd rocked back I'm forth for a little bit and then figured out how to move her arms one day. And now crawls like a pro lol
All joking aside she's just started to go forwards. Only just mind you. She takes two steps face plants then has to start again.
