Nicotine is the primary ingredient in tobacco products. Nicotine in medical products is used to aid in smoking cessation. Using a controlled amount helps reduce nicotine withdrawal symptoms when you quit smoking.
When to Expect Crawling to Begin. Babies typically begin to crawl between 6 and 10 months, although some may skip the crawling phase altogether and go straight to pulling up, cruising, and walking. Help your babe get ready for his crawling debut by giving him lots of supervised tummy time.
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.
