It can be hard not to worry I know. I'd be surprised if it was a huge problem if your bub walked before crawling - I mean, people say things about crawling being good for a child's development, but you can't force a baby to crawl can you.

And just reading again, your bub is only 8 months! That's fine! I think your first was just pretty advanced! My second bub started crawling around 9 months I think! Some kids do things early, some do things late. My first child still isn't talking at 2 years 4 months, and didn't walk til 18 months.
They're all different.
