How we practice to express emotions

Expressing emotion is another abstract concept for Aakash to understand. But he learnt to express his happiness, sad and angry feelings. Though the usage of these expressions are not consistent, he is using it in a pretty way .
In the beginning I had used pictures expressing emotions and tried to explain about the feelings, it didn’t workout for Aakash , which means Aakash couldn’t express the feelings appropriately.
So what we have been doing now is, we parents has started to express our feelings and try to associate with the happenings. For example if Aakash does something GOOD, we used to say, since Aakash behaved nicely, Mummy is HAPPY 😃 . If he does something naughty, then we say “ANGRY”.
For me, making Aakash to understand others emotions is as important as expressing his emotions.
Following is the chart we had used to teach emotions. Actually this is an old one. Now we have had added emotions like sick, upset, tired.
Now Aakash is able to express h

is emotions and also understand our emotions to some extent.
