I'd like to bus more than I do, but I've reached a compromise that works for me. I can't handle the idea of getting all three kids to the daycare on the bus. It's hard enough in the car. So I drive them there, and then park at the transit centre about 3 minutes from daycare, and take the bus for the rest of the day. We stop and do errands at the stores on the way home, if I haven't gotten them done downtown on my lunch break.
It's also heading into winter here and while I can handle waiting for a bus at -25F, I'm less inclined to stand there with three griping kids! We walk where we can in the warmer weather, but biking and walking is just beyond my comfort zone for about 5 months of the year.
Funny story: when we first moved into our house, when DD1 was 5, we were finally close enough to walk to some places. And the kids were unhappy about walking to the rec centre for their swimming lessons, but we did it anyways. Seriously, it was a 30 minute walk at a 3 year old's pace! Well, DD broke her arm in our backyard and we were getting ready to go to the hospital and she looks at me and says "Are we going to walk?! Can we pleeeease take the car?!"
I guess i'm not crunchy enough to make my daughter walk to the ER!
