I never wanted to wean my children. Weaning always seemed like curse word to me. I love the nursling/mama bond, why would I want that tot stop. I have three children, a 4 year old girl (Sally), a 2.5 year old boy (James) and a 3.5 month old baby girl (Charlotte). Charlotte is nursing and loving it and I'm not looking forward to the day when she weans. My philosophy tends to lean more to the side of child lead weaning; where the child decides when to stop nursing. While I do have a top age limit, 4 years or so, I do not practice extended breastfeeding.
My daughter Sally decided to stop nursing WAY before I was ready. She was only 15 months old and I was three months pregnant with James (yes, I've been knocked up and/or nursing for the past 5 years). She stopped cold turkey from nursing about 4-5 times a day. This was so painful for me. My breasts were engorged and sore for about a week. I remember feeling like somewhat abandoned. My baby didn't need me in the same way that she used to. She was growing up. I wasn't thinking about what my daughter needed but about what I wanted. That realization helped me a lot!
My son stopped nursing a week before Charlotte was born. I really wanted to tandem nurse (having more than one nursling). James got a stomach bug about a week before he weaned that made his poo very liquidy. When it didn't clear up after the bug, I thought it might be the colostrum that my body was producing. He was down to one nursing right before bed. I stopped offering to see if not nursing would firm up his poop. It did and he never asked about "nursies" again.
I think I was more emotionally prepared for James' weaning than I was for Sally's. It helped that there was a baby coming soon after James stopped. I have a personal goal to give my children the best start possibly by breastfeeding for at least two years. Perhaps I had a harder time when Sally stopped nursing because I didn't fulfill my "goal". The global average age of weaning is approximatley 4 years and I think that is why around the age of 4 seems to be my weaning number.
I wonder how I'll feel when Charlotte decides she's done. So far, we seem to get pregnant when our littlest is about one. We'll see if that rings true.
