Their memory improves enough to recognize people they see often, even after several days. They can get to know their family well and distinguish between praise and scolding. They can grasp small objects with their thumb and index finger and show curiosity about exploring with their hands. They can hold a cup and drink from it on their own and can open their hand and let go of an object when asked. They can explore objects in a variety of ways, such as shaking, hitting, and throwing, and can put objects in and take objects out of containers.
They can now say a few other words other than “mama” and “papa.” They are interested in colorful and vivid pictures. They respond to simple verbal requests, and use simple gestures like shaking their head for “no” or waving their hand for ”bye-bye.” They say words like "mama" and "dada/papa" and exclamations like “uh-oh.” They can also try to mimic the words that their parents or caregivers say.
They can play simple ball games and adjust their posture when dressing. They may feel shy or anxious around strangers. Sometimes they cry when their mom or dad leaves.
