Little Bit of a Rant

Ok, as all of my friends know, I am exclusively breastfeeding our daughter. While she was in NICU, I was deprived of the good bonding time and was forced to use a breastpump instead of just letting my daughter nurse. This caused issues with my milk coming in. However, after working my butt off for the first month, I finally got my supply up to snuff and have been able to store a good little bit away for when I return to work.
But here is my rant, I am sick of the in laws and my parents telling me that I am starving my child. They seem to think that she is always hungry. I have tried to laugh it off and always just say, if I was starving her then she would not be growing and gaining weight! But I swear that if it gets said one more time I am going to go off. I mean do they honestly think that I would purposefully withhold food from my child. The other thing they have been asking is when can we give her real food. Hello, but last time I checked breastmilk was real food, and I am working my butt off to make sure that I have enough milk to continue breastfeeding her. UGH....
My main worry is that when I go back to work, they are going to sneak something into her diet. Luckily Randall will have her 2 days a week, so my mom or his mom will only have her one day a week each...and since we are on such a strict schedule, and I plan on sending just the amount of breastmilk that I know she takes, then hopefully she will be okay and not starve to death...Lord help me to not go off on my parents or in laws....
