GRRR I wrote up a wonderful post and then the window froze. Here is a quick overview:
Hugs on the mastis!! That sucks.
I'm exclusivly pumping so have been doing lots of reading about pumping. which also includes increasing supply so here are my thoughts:
Pick certain feedings and pump after them like 9am, noon, and 9pm (or when you will be pumping at work). Your breasts will get use to making more milk at thoes times and you can increase your stash that way. You produce the most milk between 1 and 5AM due to the hormones in your body, if you can, add a pump in that time frame. By pumping after a feeding, you aren't taking anything from baby, you are working on increasing your supply and stash.
If you want to increase your supply pump for 5 minutes after the last milk drop falls in the pump. This tells your body to make more milk. Depending on how much milk you can get when you pump you might not need to increase your supply at all. In the first 3 months is the easiest time to increase your supply due to the hormones in your body. You can always not pump for as long if you find you don't need as much milk, but it is much harder to increase your supply if your not pumping enough (from what I've read).
After you pump you can store your pumping things in the fridge, so you don't have to wash them every time, just once a day (life saver for me!!) You can put all the milk you pump in one day in the same container and label and freeze that. I freeze my milk in Ziploc containers and use a dry erase marker for the dates. I mention this because the dry erase marker blured in the freezer and I can't read it now. Ive heard masking tape works well.
