Your baby's cognitive development in year 1
Every experience — from a simple cuddle to organized play — teaches your baby about the world. Helping your baby feel secure and engaged has been shown to increase mental aptitude. In the first few months, your baby might simply turn toward bright colors, lights, or a human voice.
As your baby's memory and attention span increase in the months ahead, he will start to apply knowledge through activity. Your baby might use his hands and mouth to explore, find hidden objects, and imitate familiar actions. By 9 to 12 months of age, your inquisitive baby craves your interaction, which further fuels cognitive development.
