My daughter skipped crawling and went straight to cruising along with furnitures (trying to reach for things at the dining table or shelves. She would rather wriggle herself over or just sit down there and ask for help. Walking wise, she only started walking on her own at 15 months without assistance. Now at 22mo, can run but occasionally choose to crawl instead (mimicking my dogs).
Try to put her favourite toys or snack at a higher place then get her to reach for it, practise daily.
