Age 2

At age 2, your child might have completed these skills:

• Language skills. Speak at least 50 words. Link two words together, such as "my cup" or "no juice." Speak clearly enough for parents or caregivers to understand about half of the words.
• Social skills. Show more independence. Become defiant. Copy others. Get excited when with other children. Engage mostly in parallel — not interactive — play with peers.
• Cognitive skills. Play simple make-believe games. Begin to sort objects by shape and color. Find hidden objects.
• Physical skills. Walk down stairs holding rail. Stand on tiptoes. Begin to run. Kick a ball.
