In my family 'full term nursing', CLW and cross-nursing is a common thing. However, when my DS continued after two years I used to then worry that he might remember nursing and might make a mention about it later on. I even discussed this with some friends of mine who laghed it over. However, later on I realized that it is not a big deal; even I was nursed beyond 6 years and my MIL used to tell that my DH had not fully weaned till he was 8 years and school going. I even remembered being nursed sometimes by two other women in the extended family when my mother was not available. One of them (who was only 20 then) later on used to remind and joke with me about it and say that she was still willing to nurse. Mostly children are discrete by nature about these matters - a wonder. My ideas later on crystallized into willingness to nurse even far beyond the normal weaning age of children should they be willing; they are afterall part of my being and have an unassailable natural relationship with me.
