ugh i hate people like that!! thats one time of the year that doesn't revolve around her and her feelings! hope she calms down.
luckily my in laws and my family are extremely supportive of our wishes. they even told us they completely understand if we don't want any visitors at all. lol we do! just not for a couple hours after LO is born since I'm a c-section too, and need to get feeling back before people come flooding in the doors to see baby.
She's calling your bluff, I think, trying to get you to back down and let her have her way. After all, she couldn't possibly care much for the baby if she's ready to throw you all out in the streets. Hold your ground, she should back down. If not, you're better off, hopefully.
