Most babies say their first word (not counting "mama" or "dada") around their first birthday.
Sight: Vision is quite well developed and a fine distinction can be made between hues. Babies of this age still prefer bright colors and also enjoy photographs, especially pictures of people who are close to them.
Hearing: At this age, Baby can distinguish not only intonations, but also words in a sentence. Baby begins to try to reproduce word sounds he hears. Great pleasure is derived from hearing his own noises and music stimulates baby to move his body.
Touch: Everything goes in the mouth! Baby has progressed from “reflex” touch to deliberate reach and touch movements.
Smell and Taste: At this age a baby's diet changes from strictly formula and/or breast milk to solid foods. New textures, flavors and smells are introduced to baby on a continuous basis during these 6 months. Baby is learning so much!
