Pumping

I started pumping today, and i wanted to know if I have to pump everytime my daughter eats, or just every 3 to 4 hours. My daughter will either eat every hour, or every couple hours, and I dont know what to do.
Also, do I pump both breasts at the same time, or just one?

i would feed on one side and then pump and store the other side then next feeding feed on the side you pumped and pump and store the other side. I did this for awhile and after a few days you will see the amount start to increase so don't be concerned if you don't pump alot at first.

Thanks!
But should I be pumping every time she feed's?

Quoting Mary Feeney:" Thanks! But should I be pumping every time she feed's?"

Yes I would or wait an hour and do it.
