My daughter is 9 mo and continues to nurse frequently when we are together. When she's in daycare (3 days/week), I pump. I've noticed recently that my supply is diminishing when I pump - I used to be able to pump 16 oz./day, and now I'm down to at most 10 oz./day. But she'll drink whatever I leave for her at daycare, so I'm concerned that I'm going to have to supplement because I can't keep up anymore.
What's going on? What should I do? I really don't want to have to supplement with formula, especially not at this stage when it's gone so beautifully for 9 months.
Also, I am almost out of frozen milk so that's got me concerned.
