Congrats Ryder!!
You are right, there seems to be a "sweet spot" around the 2 year mark. Some people miss it or their kids just aren't ready yet, but for the most part that seems to be the time. We won't really worry about it unless he is over 3 and still shows no interest, as they have to be PT'd to start school... hopefully he will take to it earlier, then we don't have to worry at all!
