How old were your babies when they started crawling or got their first pegs???

My kids were around 8 9 mos when they crawled and 5 or 6 mos for their first tooth

At exactly 8 months; army crawl. 6 months, 1 week, 3 days; central incisor (2)

7 months, I think 6 months for first tooth, then the next tooth came in the next day or two. Lol
