They criticize themselves harshly.
Third graders often overestimate their abilities, and they are easily discouraged when things don't go well. Comments like “I can’t do anything right” can be common. The pressure to be accepted by peers leads to strong emotional stress when children struggle academically and athletically.
What you should do: Make sure you are giving your child chances to accomplish things on his own without your help, which builds self-confidence in the long run. Provide challenges that aren’t too hard, such as household chores. Remind your child of things he’s learned to do; children can genuinely forget recent accomplishments because they quickly move to the next thing. Focus more on the learning process of challenges and less on the end product. If you think your child is falling behind, you can consult with teachers, counselors or your pediatrician.
