We were pretty sure colby was left-handed from fairly early on. Sure enough, he throws, eats, writes, swings, shoots a basketball left-handed.... even though all of those things have really only been modeled to him right-handed (Jimmy and I are both right-handed).
Well..... we're curious about Brendan now. He seems to favor his left hand already - about the same time we noticed with Colby.
Only time will tell!!!
