Natha still loves throwing, and the cute part about this is, when ever he does that, he seems to really enjoy it, so it is hard to discipline him on that matter. That is our problem. So, we try to teach him to differentiate between the items, balls and some toys you may throw, but not books and other larger wooden blocks which can hurt others, not sure about this, then again, he may be confused by the instructions. We just got to play by ear now, any clue about this?
