I don't post here very often, but would be happy to talk to your friend. I have 3 &1/2 yr old triplets plus a 6 yr old dd. I ap them to the best of my ability. I nursed all 3, my son weaned at 2 &1/2, & my girls at 3 (they last nursed on the morning of their 3rd birthday. I thought that was pretty cool).
We've done a variety of sleeping arrangements since they were born. They started out in cribs, then progressed with rotating them in & out of our bed. They climbed out of their cribs at 16 months, at which point we finally put a queen size mattress on the floor of their room & I would sleep with them. I night weaned them at 2 because I honestly could not handle not getting enough sleep anymore. Now they sleep in toddler beds and usually sleep all night. Many times the way I wanted to parent has not met the way I actually parent them, but I'm pretty happy with the way things have gone. I'd be happy to give your freind my email address if she wants, since I don't come to this site often.
