There is a woman in my playgroup who always has to make a comment that I'm doing the wrong thing.

I co-sleep and my baby wakes up a lot. According to her it's because "he'll wake up because he knows I'm there" and "he'll get into bad routines if I let him". Someone else said yesterday that if you let them sleep in your bed they'll still be there when they're 7!

I generally disagree, but fairly passively as I don't want to start saying too much as it'll look like a judgment on their parenting. I would just simply like to be able to be honest about the amount of sleep I am getting and get reassurance rather than judgment. I've considered leaving the group but I do enjoy chatting to many of the women there. Should I confront her? I'm not at all confrontational (esp. in my sleep deprived state)- what would I say??

What would you do?
