In case you're just tuning in, I have 3 year old twin boys - Connor and Logan.  We bought them Leapsters for Christmas, but that's another post.  However, it is relevant here.

I just had this actual conversation with the boys while they were fully engrossed in their games:

Me:  Hey guys, how's it going?
Them:  mmm ......  <clearly engrossed> ...... Good.
Me:  Havin' fun?
Them:  mmm....... Yes.
Me:  Are you guys actually learning anything playing those games?
Connor:  Yes.  Logan can't have anything to drink tonight 'cause he pees in his bed.
