The table below shows you what to expect in your child’s emotional development from 0 to 3 years. For example, a 6-month-old baby can probably see the difference between a happy face and a sad face, but not between sad, angry and fearful faces. A 12-month-old baby can probably tell the difference between how happy, sad, angry and scared faces look, but will not be able to verbally label them until 2 years old.
Please remember that there is variation between children, so some children may not be able to do all the things listed at the particular ages, and normally this is nothing to be concerned about. The information presented here is just a rough guide as to what to expect.
