When did you stop breastfeeding? After how many months?

I breastfed my children at least 2 years each. Usually i weaned them when i got pregnant again, because i know it is hard for me to attend 2 nursing children at one time. Overall, it depends on each mom's situation. Some may feel difficult to continue beyond 6 months, some have support to do it till 2-3 years. We all do what we think the best for our family.
