one possibility - is she maybe worried about you struggling to cope because of the miscarriage? I know it doesn't quite make sense but I can maybe see that someone might manage to put that together with an assumption that you might be more liable to suffer from post-natal depression, and think that maybe you need something NOW to help you cope better then. It's a bit of a long shot but it does put your sister in a better light.

another possibility - she's seen something recently (friends or neighbours perhaps, or television) and she is making a link between the poor parenting she's seen and the type of people in that case, maybe they were academics or something, and she's linking it on to your lifestyle.

definitely see if your mother knows what's going on, but go gently. I would guess that in some odd way your sister is showing concern for you, even if it isn't apparent at the moment what the connections are in her head. Otherwise, do what Rose suggests and screen your calls, limit contact with your sister for a bit so you can respond to her calmly when you're ready.

good luck Becky... isn't there always *something*!
