And even though they didn't indicate how much time had passed, those kids are young enough that they should have physically changed in some way even if it was only months later. Though I find it unlikely it had only been months. Cobb seemed pretty well established as a person who could retrieve information through dreams at that point. Too well established and familiar with life on the run if you ask me for it to have just been a few months if you ask me.
According to people who have seen multiple viewings of Inception to catch little stuff like this, the kids aren't wearing the same clothes as in the dreams. Similar, but not identical. And they're not in the same spot in the backyard either. Different positions, different time of day.

It could still be a dream that Cobb's constructed a bit differently in order to convince himself it's reality, but there are differences in the kids appearance and position at the end of the film.

As for the ring/no ring thing, apparently you can see Cobb's ring finger when he hands over his passport, and there's no ring to be seen.
