At least in my case! Theo went down to just nap and bedtime nursing sessions at around 18 months, but today (at 29 months) he is still very consistent with that. I'm not sure whether I consider it weaning or not. I think if I cut him off cold-turkey tomorrow, he'd deal with it...but on the other hand, it looks like he'll be happy to continue this as long as I let him. (The only time he asks to nurse other than in bed these days is if he's sick or really upset.)
