M. F- Congrats to you for nursing your daughter for so long. You are helping set a great example and spread the word that nursing is lovely, right, beneficial, and beautiful.
My only advice to you is to relax and be patient. I'm learning more and more that our children do things only when they're ready and they almost always have a good reason for doing or not doing something. I've read that growth of any kind can be so stimulating it's almost traumatic for babies and they will cling to what comforts them most in these times.
I see it with my son...he learns a new word or phrase or how to do something and poof...he's nuring more and sleeping less for a few days.
Ever have a day that's extra bad or extra great? Your mind just keeps going over and over it and sleep is a chore. Adults, we turn to music or comfort food or a glass of wine or something to relax us after a stimulating event. I think with children they will turn to their "fix" which is usually nursing in the brestfed baby world when things get too busy in their little heads. And at this age when they are such sponges, every day is amazing and new.
Just be patient, go with the flow, and the right thing to do for her will come to you.
And to that Glo person- shame on you. Shame. On. You. Nursing a toddler is NOT disgusting. It's perfectly natural and healthy and beneficial for both mommy and baby. There is a wealth of information in regard to the benefits of extended nursing but that information is kept in these things called books. Something you don't seem to have heard of judging by your ignorant post.
