My daughter is 10 months old. She has not started to crawl. What should I do?

Crawling at 10 months old is just a guideline. Some babies will crawl even earlier than 10 months and some babies will crawl later. Please give your little one some times to develop his own milestones. Some babies will even skip crawling stage and proceed to walking stage. http://www.todaysparent.com/baby/why-babies-skip-crawling/
