@eecuadrado: This blog has SO MUCH INFO: http://exclusivepumpers.com/2013/03/
It is geared towards exclusive pumpers, but a lot of the tips and tricks apply to those who choose to pump while at work and nurse at home.
First, spend maternity leave establishing a supply, and when you feel up to it, beginning a freezer stash for baby when you first go back to work.
Hydrate, eat well, rest when you can.
Here’s a run down of what I did:
I pumped into bottles during the day, and stored them directly in the fridge. At the end of the day, I set up the following day’s bottles using what I pumped that day.
If I had extra, I froze it. I decided to freeze in 4oz increments. Some people do more, some less, some do a combination. I loved the Target brand breast milk storage bags… cheap, durable, and easy to thaw. I liked to freeze the bags flat overnight and then stack the flat bags in a taller freezer bag for easy storage. I labeled everything so I would know to thaw them in order.
If you do end up with a significant oversupply, you’ll want to look into getting a chest freezer. Frozen Bridesmaid or Best Man is good for 3-6 months in a fridge freezer, but good up to a year in a deep freezer.
Hope this helps some, and if you have any specific questions feel free to ask!
Oh, and as for getting space at work to pump, I’m sure working in a legal setting they will be willing to accommodate your needs, since it’s federal law and all 🙂
ETA- depending on your commute to and from work, you may want to get a car adapter so you can pump in the car. I used a hands-free bra, a nursing cover, and my car adapter. You will also want to get Medela steam sterilizer bags. Between pumps you can put your rinsed parts in the fridge in a bag but you definitely want to CLEAN clean them at least every other pump. If you have a bunch of male coworkers, it might be best to steam the parts and let them air dry in your “pumping room” or wherever is less awkward.
