I've had an oversupply since LO was about two weeks old, and have had to pump regularly to keep my levels manageable for her... When I'm home I usually block nurse one side and pump the other.
I haven't wanted to reduce my supply to match her demand, because I work full time and wanted to have a huge freezer stash, plus I'd heard from people that your supply drops when you're at work.
I'm super lucky, BTW, since my nanny brings the baby to my office at lunch (along with a sandwich for me) so LO and I have a special lunch date every day.
She's 5 1/2 mos now and will be starting rice cereal in a few weeks, so I think I can probably start reducing my pumping sessions at work. She only eats 5-7 oz while away from me all day, partly because she's reverse cycling a bit and because I think she "saves her appetite" for our lunch meetings.
Right now I'm pumping double what she needs... My freezer is full. Milk banks in Korea won't take "foreigner" milk, and there's really no where for it to go... is it time to cut out one of my daytime pumping sessions? It'll take a week or two to reduce my supply because if I go straight from morning to feeding her at lunch, my OALD will kick in and she'll sputter and spit up.
Should I let my supply dwindle to match her demand now? Have I done enough to make sure she's set?
Or alternately (as my husband suggests) I take the extra I pump during the work day and he gives her one bottle at night. (She feeds every 2-4 hours at night.)
