He actually has a 1 1/2 year old brother.
The excessive use of video games is in your hands, also computer gamnes it sounds too much especially as he is only 5 year old, is there something he is upset about, has he aan older sibling?
You can build in "breaks" into his playing video games schedule - maybe set a timer......
Limiting video games may do the trick as well......do not forget that he is only five
You might want to google encropesis. If this was a one time thing - I wouldn't be too concerned but if it is ongoing - this could be his problem..
