Give yourself a break you've only just had a baby!!!

Here are some of my suggestions.

On a hot day fill up a baby pool with water and balls. Let your toddler have a paddle.
Get out for a walk
Go to the local park
Put on a kids music cd and go for it
Go to a playgroup

My DD1 is a very active child and needs to get out of the house even if it is for 20 mins in the arvo.
