Pumping Question (while at work)

mbtortor

DD is EBF and I pump 3x a day while I am at work for the 3 bottles she gets at daycare.  All other times, I BF her.  With DD1, I quickly went to 2 pumpings a day and used formula to make up for what I wasnt producing.  And the days I was with her, she would get a bottle of formula, since I felt I wasnt making milk at that time slot.  I want to start pumping 2x a day now too because it just takes too much time out of my day.  I'll eventually go through my freezer stash and will have to suppliment with formula, which is fine.  My question is, when

I am with her, can I nurse her 3 times even
