We are still, and I don't expect that we'll wean anytime soon. I expect we'll go well into the 2's and maybe 3, but I guess we'll see what he thinks, maybe he'll surprise me and want to be done sooner. I helped my DD wean when she was 3y10mo (I was ready to be done then), though she would have loved to continue, so sometimes they just really love/need/want it for a long time.
The book "How Weaning Happens" is really good. Def check it out!
