“Feeling bored is a common experience for most school-age children and can be attributed to many factors. For example, children may verbalise that they are feeling bored when they feel lonely, discouraged, confused, overwhelmed, or ambivalent about an activity or disappointed by the outcome of play activities.”
The toys you used to play with arn’t fun anymore.
Decide how you feel then look at other possible activities, perhaps make a completely new way of playing with your toys. Look at the situation from different perspectives.
