Cognitive development
Your child starts to distinguish opposites. He also understands instructions that involve two separate actions, such as "Drink your milk and give the bottle to mummy." He can now more clearly describe his needs.
Speech development
Your child is now able to hum his favourite tune, tell you what he is doing, and express likes and dislikes. At this point, "No" may be his favourite word.
Motor development
Your child can hold a crayon to draw simple lines. He can also play with a ball, eat with his fingers and walk without support. In no time, he will be able to carry his toy while he walks. He will also discover his ability to run.
Social development
Your child may demand your attention, asking you to play with him. When he grows more self-assured, he will look up to older children, play with them and mimic their actions. He may also form relationships and play with children his age.
