We have cut our Ben 10 for our boys 6 and 4 because it has created problems. Unfortunatly age appropriate tv seems really boring to them for awhile as they settle back. Now the watch wiggle and playschool then tv off. In the afternoon maybe a dvd.
There are other programmes that are age appropriate too, personally i don't like the wiggles but...
Our boys seriously played up and took me ages to realise that Hubby was letting them watch anything.
Your boy is also at the age when they start noticing the world around them in a proper way.
Is anything else going on that may be upsetting for him?
its awful when this starts happening but lots of kids go through a violent patch

Sorry if it doesn't make sense, the barefoot princess is covering me with kisses
