I do when asked about LO. I'll fudge his age a little to avoid getting the preemie questions. If asked about breastfeeding, I just say it's great and that it always has been, if pressed for details (though we struggled really badly in the beginning). If asked how he sleeps, I say wonderfully (he gets up 1-2x a night and sometimes has a really bad night like last night... He just wanted to nurse alllll night).

Do you lie to strangers? I just find it easier than saying that its none of their business (I would feel really rude saying that!)
