Louise, Those weaning ages are population based averages. Our children know what is right for them, but sometimes it is hard for us! If your son seems content not to breastfeed, it is probably weaning, if he is upset about not nursing, this might be a nursing strike. If it is a nursing strike, he might nurse in his sleep.... Some children wean before 2 years even with moms that are around full time.... My son weaned at 22 mos, my daughter nursed almost 4 years. I did everything pretty much the same....they are still very different little people. I'd like to avoid a "cultural mileau" among Lactnetters or bf supporters that penalizes mothers who nursed for shorter periods of time. Nursing for 21 months is nothing to be ashamed of!
