Human faces are one of an infant's favorite and fascinating things to observe, especially when it's mom or dad or his own image staring back at him in a mirror. By 3-months-old, most babies know the difference between familiar faces and strange ones.
Starting at around 3 months of age, infants begin to show outward signs that baby teeth are coming. They produce more saliva and will put their fingers in their mouths. This drooling can go on for several weeks before you'll see a tooth. Infants typically get their first tooth between ages 5 and 12 months. The bottom incisors emerge first, followed by the top incisors. Usually around 2 years of age, a toddler has a full set of teeth, explains Dr. Edward Kulich of New York, NY.
