I take my group of 5 children out walking for a couple of kilometers at least 2X a week and we take the bus at least 1X a week. I always have the two smallest children in a tandem double stroller. My 3 older children walk and I started teaching them how to walk with me by the stroller shortly after they turned about 18 months or were strong walkers. I bought the backpacks at Walmart that are puppies, ponies, etc. and they have long strings that attach to my wrists. It takes lots of practice but my youngest walker just turned 2 this month and he's doing fantastic and we are able to go all over the place. I would go crazy if we couldn't go out on field trips and the children love to go different places all the time.
