Clothing Affects Crawling
The way your baby crawls could also be influenced by the clothing he is wearing. At the turn of the century, babies crawled by using their arms to pull their bottoms across the floor because their long dresses got in the way. Clothing still makes a difference today, says Campos. "Babies who are born in the winter and hence begin to reach the stage of crawling in the summer will crawl earlier by 4 weeks than babies who are born in the summer and learn to crawl in the winter," he says. "That's because winter crawlers are more likely to be wearing heavy clothes." And that's going to get in the way of practicing certain skills. So take off those socks, strip your baby down to his bodysuit, and let him explore.
