Finally able to use my pump. I have been hand expressing because when I first started using the pump, they gave me too big of cups so my nipples got cut up and bruised. Now I have the right size and since I hadn't pumped through last night, I have already filled up two 35ml bottles and I'm on my second ones. Oh I feel like a cow but in a good way. I am producing so much and it is all for my son. Makes me feel good about myself as a mother. :)
