When did baby crawl/walk

Lacey

How old was your little one when thet started crawling and walking. We're almost 9 months and she's up on all fours but cant figure it out, can scoot on her belly backwards.

Can stand and furniture walk if you put her on her feet. Still not able to get into sitting position on her own though. She's royally pissed about not being able to move and gets so upset trying.
