growing up I lived in a small street which was full of kids. We all played at the park, we all were able to see behaviour in other kids. We could see other siblings getting along or not getting along. We developed our sense of right and right from these situations.
Now fast forward to my kids being of that age. We live in an area which is full of retirees (no kids), we have to drive to school, the kids go to after school care and we don't spend time with family (let's just say their lives are just as busy as ours).
We have been looking for years to find a house close to the kids school, in an area full of families and it's just way out of our budget.
The reality of how it affects my children weighs heavily on us, especially when I can see that it's the key to a big part of a social skill they really need at this age.
I would love to hear from you as to how you work around this for your kids.
