There is a spot in our school where the classrooms and verandahs make a little tunnel about 10m long. The kids all love the echoey sound and it’s common to see them popping in and out and giggling madly. The little girl noticed it the other day when we were walking through the school and [...]

Greening My Home

April 20, 2012 Babies

On Tuesday I posted about ways to save energy at home with practical tips. Today I thought I’d look at our home and make some public commitments of things I can realistically change.
