P.M.
I've bed-shared with my daughter since birth. She's 5 y/o now and has made the decision to start trying to go to bed in her room and new bed. We happily supported this change, and made a big deal out of it.
These years are so short, and you can never get them back. Co-sleeping isn't a chore, but a part of billions of Mothers daily lives everywhere. Enjoy it while you can... and allow your daughter to enjoy the love and comfort it gives too.
