Mommies who's babies are crawling...

If your babies are crawling did they start off army crawling first, or did they go straight into crawling on their hands and knees? I'm asking because my daughter is not interested in being on her stomach at all. She will be 8 months on the 26th and still hates tummy-time. She won't even roll over. I'm not sure if army crawling is the first step to actual crawling. If so, we're in trouble. 😓
