It's hard to say. But don't lose hope just yet - my friends twins did this at about 14 months. It was like the more she offered the more they refused. So what she did was just offer the feed they were most interested in. If they asked, then she'd feed them but if not they were only having one feed a day. This went on for months and months and they finally completely weaned at 2.5! So you could still have a way to go yet.

Big for you though. I know what it's like when they wean, it's so sad for us mummies, especially if you don't reach the goal you had set in your head I keep hoping that DS will wean soon because I think about 3yrs is my limit and I am tandem feeding but he's showing no signs yet. We've also been on one feed a day for a long time now, so it is possible.

I hope he hangs in there with you
