Believe it or not, a small child may express anxiety and concern even for the most basic tasks and day-to-day, as well as to be with other people or attend an event. How do I help you?
Your anxiety may be a reflection of yours
Anxiety is hereditary in some cases, and in addition, it is learnt. If you or the father are anxious, the child will be more vulnerable to experience these feelings. It's not about blame, but it is good to recognize this fact to avoid habits that may increase the stress or pass it on worries and anxieties.
Experts in child psychology recommend that you do not delete the routine which generates anxiety, since you would disable the small to solve their problems. Similarly, you should not press the child to stop expressing anxiety, even verbally.
One way to demonstrate calm and help the child with GAD is to transmit tranquility, in the way you talk and behave when you're with him. Point out how you have managed to overcome obstacles bravely in the past and that you understand what happens.
Another important thing is that the child understands what things cause you anxiety. In this sense, it is effective to carry the child to a psychologist or a professional to help you periodically and teach him how to regulate their disorder and lead a normal life.
You can also communicate with you about your problem in school, for teachers to understand their behavior and can help, avoiding things that cause you distress (such as speaking or reading in public).
If you're going through this situation, do not worry in excess; for help and trust that with time you'll be able to ensure the emotional well being of your little one.
