Definitely not bad for him. My daughter started crawling properly at 11 months, and it lasted till she was 17 months when she started walking. Before that she commando crawled everywhere. But she was standing. I got told some pretty awful things like because she didn't crawl properly she would lack motor skills, and that she would have physical problems. I then read in a magazine how a famous female swimmer only ever commando crawled and then walked and she had competed in the olympics
