Okay, wow, well it is going to be really hard as others have said. I did it but honestly I only lasted for 5 months or so. Maybe 4? It's all a blur!
I had a medela pump in style, but the suggestion of renting or buying a hospital grade pump is something to consider.
Where to begin...here were my must haves:
1. a giant tub of Lanolin...order it from the pharmacy and it will only cost about $10 for a pound. The small little tubes are only going to last a week or so and are at least $4-5 each. You can put it on your nipples/breasts but I also rubbed it inside the falange of the pump and it felt better. The lactation consultatnt gave me this idea so it's safe.
2. a hands free boustier (sp?). It is a MUST! This way you can pump and feed at the same time. Or you can pump and read a book, type, diaper...I even knew someone who pumped and drove...no joke!
3. Soothie pads....they are expensive but you can find them at CVS and Walgreens. I used them when my nipples were really raw.
4. Fenugreek....it's an herb that helps to keep your milk supply up. You can buy it at a health food store. It will make you smell like maple syrup which is weird but true.
5. Medela easy steam bags for the pump parts...I used these more at the beginning but then I just started washing the parts after each use with good ol' soap and water. I was too tired in the middle of the night. I did this for many weeks at a time and my kids never got sick and I never got mildew or anything. But, I did use the bags every few weeks to get a "good" clean.
As far as keeping stuff in the freezer, fridge, etc. I had a stock pile in the freezer. But, when my babies were brand new they were waking up every few hours anyway I would just pump and then leave my milk out in the bottle right in their room so that it was easy to access and room temp. I think that milk can stay out for 4 hours. I'm a little rusty on my breastmilk time tables, it's been a while. When they started sleeping longer I would take it down and put it in the fridge. I trained my kiddos to drink cold milk as soon as I could b/c it's easier and it's faster and when you have to diaper, feed, pump, and clean multiple times in the middle of the night, it's a life saver.
As far as thawed breastmilk, it's pretty quick to thaw in a cup of hot water so I'd do it shortly before each feeding if possible. Others mentioned it only keeps 24 hours in the fridge after it's been frozen and that is so true! I accidentally gave my son some very spoiled milk after I had forgotten that rule from my first pregnancy, so after that I tried to do it on demand! ;)
Good luck!
