I know you are getting tons of advice (not to mention unwanted belly rubs and comments) so take this post with a grain of salt.
I am going to tell you the best piece of advice I ever got. And it wasn't from a friend or from my sisters or my mom (sorry mom you do give good advice though). This piece of advice came from a patient's wife at work. I was about 30+ weeks pregnant and was sick and tired of the comments I was getting. "Wow, you're really big for having so far still to go."... "Looks like you will be going on an extreme weight loss program soon."... "Be sure to put your baby to sleep on her tummy!"... "Be sure to put your baby to sleep on her back!"...
You can imagine my disgruntled nature when this lady said, "I am going to give you the best piece of advice." She could see my reluctance in believing that she, a stranger, could have any advice for me that was "the best." But it was. "No really, I know you are getting lots of unsolicited advice from people but this is going to be the best one I promise."
"OK" I said.
"Regardless of what ANYONE else says, your mother, you mother-in-law, your friends ANYONE... Do what YOU feel is best for you and YOUR baby."
And my jaw hit the floor.
You see, when Charlotte was born I had all sorts of opinions and ideas about what I would do as a mother. They become in a sense my "commandments" before she came.
But you know what? I'm doing what I feel is right for me and for her- regardless of what anyone else says... and it feels good. Regardless of what I have read in books too (yeah so she is now 9 weeks old and doesn't sleep through the night when they said she should by 6 weeks- whatever she will get there!) She is healthy and happy and developing well.
So new mama's all I can say is hang in there. Do the best you can. Enjoy the good moments and survive the not so good ones. You and your baby are both learning. Love them, snuggle them and let them be little. It doesn't last forever.
