Hi lotusdebi!
My nursling is almost 3 1/2, and #2 will be here any minute, so I will be tandem nursing for the foreseeable future. I consider myself a CLWer even though I
1) recently nightweaned during my pregnancy to prevent my complete transformation into an ogre
2) have said things like "I'm eating my supper right now. We will have nana when I'm done eating."
3) instituted a "no-nursing while mommy is sitting on the toilet" rule

4) only allow twiddling at home

My son still has almost-unfettered access to the boob, and I certainly feel that his nursing needs are more than adequately met (I'm pretty sure he does too). As one poster said, all relationships require boundaries. I am a sensitive and loving parent. I am not a doormat.
Anyway, glad to see so many sustained nursers here.
