One of the best things about being a child is

those times when you get to play “Grown Ups”.  

 Let your kids use your digital camera.  Give them some guidlines for use and let them roam free in your garden. 

Depending on their age, they will be able to download and edit the pics for extra fun. 
 Children are able to see beauty and life everywhere and often surprise you with their results.  Plus it is amazing how quite they are when they are bird and bug watching.

I bet you could use the peace and quiet.
