just wanted to agree with what everyone else said....dont listen to her, there are so many different ways to raise children and im sure hers (if she has any) are fine being raised that way, but that doesnt mean that you have to do it her way! you trust what you think and do what feels right for YOU, no matter what book or nurse tells you otherwise! It sounds like you are doing the same sort of things i did with my DD, i wore her for a lot of the time in the first few month and a few of my friends thought i was crazy, but DD is such a happy, content baby, everyone comments on how happy she is! just hope that next time you see your normal nurse!!
and it sounds like your doing a fantastic job!!!
