I'm in the process of weaning off the pump and this week I went down to one session. I am engorged by lunchtime (when I pump). I think part of the problem is she isn't nursing very well in the morning. Stuffy nose combined with distracted and wanting to go to daddy and play with her sister. So she's not emptying.
My plan was to pump once a day for a week then be done by Friday.

Should I pump for another week at once a day? I'm afraid I won't be able to go all day, just yet, without pumping and not being painfully engorged by the end of the day!

With my first my pump supply dropped to nothing so it was no big deal to drop!
