How often to pump?

jyoung01

I'm a working mama and my kiddo is 5 months old today.  I pump at work and send the milk to daycare.  Right now I'm pumping at 9:00, 12:00, and 3:00.  Pumping 3 times is really becoming a hassle for me and I'm trying to decide if I can knock my pumping down to twice during the work day.  What's everybody else do?  Any suggestions?  I really don't want to mess up my supply and I don't want to cut out the 9:00 pumping because I'm usually still really full from the night (even after nursing the baby before daycare).
