Don't commute with the kids yet. Our son goes to pre-school mid-day so it's not yet practical. Also, when he does start school full time, the local elementary school is only a block away, so we'll maybe ride together, lock up his bike, and then I'll continue on. Our daughter is 9 weeks old; no commuting for her for at least a couple of years.
One thing I know for sure; for as long as my son can remember, "dad" gets up in the morning, puts on his kit, and rides to work. It's completely normal to him that someone rides their bike to work. As he gets older, I hope to impress upon him that riding a bike is a viable alternative to using a car, especially in a town the size of Victoria where virtually nothing is more than 5 miles away.
BTW.... love the creme Fat Franks. It's one of my favorite tires.
