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.

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!
How babies learn to crawl. Your baby will likely start crawling soon after he's able to sit well without support (probably by the time he's 8 months old). After this point, he can hold his head up to look around, and his arm, leg, and back muscles are strong enough to keep him from falling on the floor when he gets up on his hands and knees.
