Nicotine, which is the main drug in tobacco products, is the number one used drug in the U.S. Many people do not consider nicotine to be a drug, however it is. Nicotine is highly addictive and has the properties of both a stimulant and a sedative.
Your baby will probably be able to lift her head when she's about a month old, and hold it up when placed in a sitting position at around 4 months. Her neck muscles and head control should be strong and steady by 6 months.
Parents often wonder what toys are best for babies. At around 2 months babies are learning to use their neck and shoulder muscles. They soon will begin trying to raise their heads when lying down and to reach out for objects when sitting. You can hold toys out in front of your baby to encourage him or her to reach.
