My son hated it, so we didn't do it. He was holding his head up at birth, and as others have said I DID hold him in all positions of the rainbow. Even after he started speed-crawling, he still never spent any time on his stomach. Even as an 8yo he doesn't lay on his stomach for longer than a minute or two, he lounges on his back, with his feet kicked up. That position annoys ME, I lounge on my stomach or side. We all have different likes/inclinations.
Some babies never crawl. They go from sitting to walking. Others (like my son) crawled at the speed of light for MONTHS, and avoid walking because it was too slow (my son almost never walked, and even now rarely walks, he tends to run/skip/jump/slide, but will walk if I'm holding hands with him).
