Because I competed yesterday, I had my dad take my son to the kids' class yesterday. He was impressed with the skill and patience Sensei exercised with my son. He also told me that my son has very little Zitsfleisch (A Yiddish term for patience or attention span). I explained to him that as bad as my son might have seemed yesterday, his attention span has grown exponentially over the past two months since he started Judo.
My son also mentioned that he had a new 'partner' in class, as one more younger sibling of one of our current students started Judo. In addition to that, at the tournament I ran into two more dojomates - one who's family just returned from a few months overseas, and one who's son is turning six - that they are going to enroll their kids for the next semester. This is awesome, I love that the kids class is growing, and that the number of kids the same age as my son is growing too. Sensei is looking to add a second kids class during the week, which will hopefully bolster attendance.
