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.
Baby-proof early. Crawling is preceded by rolling over, according to Pediatrician Tracey Drummond, M.D., of East Scottsdale Medical Care. She insists that you should start babyproofing your home at this time, before he is actually on the move, since it will take a little bit of time to complete the baby-proofing process.
