Bottom line
Every baby develops at their own pace. The milestones listed for 10 months old are typical ranges based on CDC and AAP guidelines. If your baby hasn't reached a milestone, it doesn't necessarily mean something is wrong — but talk to your pediatrician if you have concerns.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.
