Just wondering!
My DDs (2.4 and 0.7) are such light sleepers that I wouldn't dare. DD1 is ill at the moment and I had a crisis of conscience last night about whether I should check on her before we went to bed. But then I reasoned that if she needed us, got worse, or was sick, she would cry anyway, so we would go in then (and they both have monitors in their rooms so we would hear them wherever we were in the house). Surely all checking would achieve would be waking up a little girl who needed her sleep?
I can see that it would be lovely to look on your little sleeping angels (if they didn't wake up), but isn't that more for the parents' benefit rather than the child's? Or am I being a bad mum not looking in on them?
