For rainfall in Cancun there are monthly totals of the number of days with wet weather and for the amount of rain it receives. Besides these averages, there are also data on how much a month's precipitation can vary from year to year. The averages for temperature and rainfall are from weather data collected during 1981 to 2010.
COMMENTS () | PRINT. If you're a first-time mom, you're probably anxious for your baby to start crawling (if this is your second child, the thought of babyproofing your older child's toys probably fills you with dread!). Some babies start crawling at about six months, some use unique methods to get around, and some never crawl at all!
While 9 months is the average age that babies start to crawl, it's neither unusual nor abnormal for babies to put off crawling until 11 or 12 months -- or in some cases, not crawl at all. Two main factors seem to influence when babies crawl: 1. Baby's personality. Babies with mellow or laid-back personalities generally tend to sit up, crawl, and walk a month or so later than hyper or motor babies who can't wait to move. Instead, mellow babies tend to be earlier in their visual and social development.
