My daughter is two and we've just started the weaning process. I, like you, am so sad about it. I don't want this special time to end, and my little one doesn't seem interested in giving it up, either. I'm trying to do things gradually for her sake and my own. We've moved to bedtime and first thing in the morning only. I'm trying to focus on the benefits of moving on to the next stage with my LO. It's fun to watch her language continue to develop and to find new ways to interact and bond with each other.
I feel this way as well. My 14 month old began self-weaning soon after his first birthday. I was very sad about it and although I don't want to hold him back, I feel pangs of sadness when I think about this chapter of our lives coming to a close. He was down to just nursing at nap/nighttime, but about a week and a half ago he started nursing once mid-morning and mid-afternoon again. I am relishing these moments as I know they won't last a whole lot longer. I try to enjoy each phase he goes through knowing that we have built a bond that will last a lifetime. Congrats on nursing this long and good luck in the coming phases :)
