When we are talking about anxiety in children, it is seen more or less between the age of 4 to 6 , if not tackled appropriately then it becomes a habit. But how do we makeout? So here are the pointers to check.
1) Sudden response which is negative , to things which were always liked.
2) Being fearful more often than before.
3) often complain about stomach ache without any particular reason.
4) Headaches.
5) Nauseating often.
6) Disorder in sleep patterns.
7) More talkative child has gone a little silent.
8) Less playful all of a sudden.
If any of these symptoms are seen, you need to get a little alert, parents and try to talk to the child.

Multiple reasons like stopping the breast feeding abruptly, abruptly stopping the bottle if ever given in young age to feed milk to the child, change of house, change of school, taking off the shawl or favourite toy which was with the child right from his toddler age. Often loud arguments between the family members in front of the child, separation of parents, death of a family if witnessed closely and many more.

Multiple ways to tackle it. 1) Observe it , differentiate it well before you take any step.
2) Is the incident happened or its virtually witnessed by the child or heard
3) Talk to the child , addressing as a different segment and not as a behavioral issue.
4) Explain about the behavior change that was noticed.
5) Less questions and more emphatic listening.
6) Explain what consequences are of the new behavior the child has adapted too.
7) Make a strategy together. 8) Use the language of we then I.
9) Explain the child’s strengths.

To add to the above listen symptoms, they withdraw socially, go reactive to situations, show anger tantrums, have severe mood swings, are more conscious about things and people and their comments, are less participative in family gatherings or even during meal time and also sleep disorder.

No, but variation in food habits certainly is a case of anxiety if clubbed with few more behavioral changes.

Absolutely. It does. There are multiple ways to tackle it. 1) Observe it , differentiate it well before you take any step.
2) Has the incident happened or its virtually witnessed by the child or heard?
3) Talk to the child , addressing as a different segment and not as a behavioral issue.
4) explain them about the behavior change that was noticed.
5) Less questions and more emphatic listening.
6) Explain what consequences are of the new behavior the child has adapted too.
7) Make a strategy together. 8) Use the language of we then I.
9) Explain the child’s strengths. Adding to these, Affirmations, positive strokes work.
If the child is an adolescent or a teen, involve in house matters, albeit age appropriate. Immediate family outings , increase or make a regular affair, don’t tag or bag. If not able to tackle, take professional help, enroll the child in a sport and one of the parents can enroll himself as well, that gives a sense of belongingness in a child.

There can be various reasons to it. You need to observe and check the trigger to this behaviour.

Giving in to the demands may give rise to many behavioral issues in a child. If you feel that the child is anxious , you can divert a little towards things the child likes, it may be indoors or outdoors but outdoor works better. Try all tactics except to give in the situation. And since they don’t have a vocabulary or power as we adults have, they do everything wherein they get their deal using crying, tantrums, or loviedovie behaviour as tools. Again, it’s cute to see them doing all sort of arrangement or ‘jugaad’ to get their things done, but as a parent we need to ensure that that isn’t adapted as a behaviour.
