First, I wouldn't say "mistake"....holding your baby while asleep is not wrong!!! Its all about what you can do to survive and nurture your child at the time - so now that the co-sleeping is not working for you anymore because the baby is getting bigger (or whatever the reason may be), you can train the kid to do something else. :) We started with our first daughter getting her out of our bed when we were pregnant with our second, she was a little under 2. We sat with her by her little toddler bed until she fell asleep.....I still sit with both girls, now 5 and 2 1/2 while they fall asleep. That doesn't work for everyone and some may even say I am not "teaching the skill" of falling asleep on their own....but seriously, i know alot of moms who have done the same thing and they don't have 18 year old children that can't fall asleep without their mommy. It all works out. If yo want her to fall asleep BY herself, you might just have to go in stages, and it will not be easy - but surely its doable and kids CAN be taught things even when you think the window of learning has passed.....
