Oldest weaned (stopped asking) after 4 1/2, though I don't think there was a certain day when I realized it had happened. I do recall thinking it would NEVER happen though! He has asked to nurse since then (it's the "cool" thing to do around here, I guess
) , but more as "just checking" and though i have let him nurse a few minutes, I consider him weaned as it was several months ago and he is 6 now.
Middle guy still asks to nurse every couple of days or sneaks in a nursing in the early morning occasionally (maybe three times a week?) He will be 5 in January.
Youngest is 2 and nursing at nap and bedtime, less interested since my milk production stopped during this pregnancy. I am sure we'll have lots more nursing time with him when the baby is born!
