Pretty much back to normal

I am back at work after a successful weekend of nursing. Baby Ben got one bottle of expressed breastmilk to give me a little break but that was it. I am pumping at work right now. Mondays are always the worst. have to get back in the swing oj pumping after having the weekend off. I have noticed that he will nurse real quickly and be done in about five minutes and be good for hours sometimes. I wonder if he is really getting enough. Then I step back and remember that even if he eats less it is of such high quality he doesn't need as much. I still keep those formula checklist in the back of my head. I need to clear them out!
