Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old. But doctors in the United States now say babies begin learning on their first day of life.

A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other people.

The researchers say this ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers.

Experts say the first three years of a child’s life are the most intensive period of language and speech development. This is the time when the brain is developing. Language and communication skills are believed to develop best in an environment that is rich with sounds and sights. Experts say babies should repeatedly hear the speech and language of other people.

America’s National Institutes of Health says evidence suggests there are important periods of speech and language development in children. The ability to learn a language will be more difficult if these periods pass without early contact with a language.

The first signs of communication happen during the first few days of life, when a baby learns that crying will bring food and attention. Research shows that most children recognize the general sounds of their native language by six months of age. By that time, a baby usually begins to make sounds. These sounds become a kind of nonsense speech over time.
