*great big hugs* to all of you!
just wanted to add a little note, perhaps taking the time to talk to your parents/inlaws about your expectations for them may help. I have a very supportive husband who was willing to spell out the 'rules' for his mother.
I remember one time when she had said something very hurtful and negative to my one month old dear son (indirectly about me), he saw my face and stepped in to tell her that it was our son and we would bring him up the way we chose.
I thinks that's an important point to remind them about family units. Basically, because they have their own way of doing things and see us as 'newbies' when it comes to parenting. They dont't realise that they are crossing boundaries that shouldn't be crossed.
As for moms who say baby doesn't have enough milk. I squirted my mom several times until she got the point and stopped making such comments. After all, if I have enough milk to squirt at her... I should have enough milk right? Yes I know it was kinda rude but what else to do?
