Questions for those who have pumped at work

skroops

I am already starting to stress about how I am going to manage pumping when I go back to work.  I never pumped at work with Zoey because she over a year when I went back and so I never had to send any bottles to daycare.  I feel so clueless when it comes to pumping and bottle feeding, so I hope you ladies can give me some insight.  I know I have a few more months before I really have to worry about this, but my type-A personality wants to know what my "plan of attack" will be.  lol

Liana will be about 7 months when I start teaching again in Sept.  I will probably be away from her about 7:30am to about 4:30 pm figuring in the time to get to and from work.  How many bottles do you think I would need to send for that time?  And how many oz per bottle?  How many times do you think I should try to pump during the day?  I have no idea how this is all going to work out and I am worried about how I am going to fit teaching, travelling between the two buildings, and pumping into my day. 

Thanks for any insight or advice you can give me.
