My oldest weaned, with encouragement, at 38 months, after tandem nursing with her sister for 9 months.

I am currently tandeming again, with a 6 month old and 26 month old. The 26 month old is only allowed to nurse 3 times a day (morning, nap, bedtime) or when I offer. At the very least, you can put limits on your nursing, so that you can feel better about it. Tandem nursing can be very exhausting.
