My 11-month-old has started refusing to nurse, even to latch in her sleep, since yesterday. We had been going on 2-3 months of pretty blissful nursing (no bottles, I stay home) after a long rough period with lots of "mini-strikes," so this came as a surprise, though I know it is common around this time. She is cutting teeth so I am hopeful it is related to that and temporary, however, she will suck from a sippy cup and suck on her thumb just fine, and she is not necessarily unhappy about not nursing. She is just hungry! She doesn't take much (expressed breastmilk) from the cup. She's had maybe 3-4 oz since she last nursed at 4 yesterday.
I only have a manual pump and if this continues through today, I think I'll want to rent a double electric to get us to the one year point at least. How many times a day and for how long would I need to pump to maintain supply for her at this point? Is it true that my body is more likely to interpret periods like this as weaning, and so I need to be extra careful, or is the reverse true? Thanks so much for any advice.
