A.S.
My first self weaned at 29 months...it had been bedtime only for a long time....you shouldn't experience any discomfort. My youngest is still nursing as well and I just spent 3 days away from him without pumping or anything and I was fine as well. You may have milk for a long time afterward cause your body got so used to making it, but at that age they aren't taking much anyway so there is no discomfort.
