oh is there an 'officially correct age' for weaning?

i'll be honest, my kids went through their first weaning as soon as they cut teeth. i am just not a loving enough mother to get bitten (twice).

but my DIL didn't wean my granddaughter till she was close to 3-- and late weaning (3 or more years) is not uncommon in many cultures.

i sometimes think kids aren't fully weaned till the are seperated from their parents by death. i know i still get called in to provide 'motherly support and comfort' by my children. (not often, but still) and expect i will be doing so at odd intervals for the rest of my life.
