Hi! Your boys sound very much like my DS-now-5 was at that age. For him, the next step was spelling obsession about age 2.5, followed quickly by obvious reading (i.e., I know he read at least a few words before 2, but I'm not sure when he developed more, because for a long time most of what I saw him do was explainable by memory and I felt squeamish about testing my 2yo to see how much he could read, so I didn't!) Do yours quote chunks of their memorised stories, sometimes changing the character names to suit e.g. toys they have at hand? DS used to do that for a long time, and I found it hilarious.
My singleton DS really didn't talk until a few weeks before he turned 2, but also I think I remember hearing that twins are quite often late talkers because they develop ways of communicating between themselves which are not comprehensible to other people, sometimes a full "twin language". Do yours do that?
