Hon, im exactly the same, i have a lil voice inside my head that says 'your not doing enough'. Im a SAHM and do heaps with my girls too, we play outside, do craft time, go to shops - etc, etc. Family members often joke that we are the 'three musketers' - coz we're always together and always doing something.....why isnt it still enough? Like Lucy said, mothers guilt.....its hard to shake those feelings, esp whilst cooking another. Sometimes we are our own worst enemies.....it sounds like your doing great by the way !!!
