Same as you, BB refused my nipple since 8mths, not even one bit :-( . After switch to full-pump, milk supply is decreasing, may be I am lazy and pump less now just 2 times per day.
Now BB is 10.5mths, enjoy Mama milk for 1.5meals daily. I also thinking about quit for many times...also milk supply further decrease due to period...But it is very very hard decision. As milk could not resume...
try your best and relax! You've done a good job already!
anyway everyone, including your bb, has his/her developmental stage.
I breastfed my 3rd kid up to 1.5 years and am quite jealous of other mothers who could breastfeed their kids up to 2 years old or even 3 years old but I just accepted it. From the good side, I have improved a lot (I could only breastfeed my 1st kid for 2 months, for my 2nd kid, I breastfed for almost 11 mths)
