Just noticed last night that when we say "ds1 choose" he has actually started to consistently. He has sussed out that he can choose a diffeent video at bedtime each night (before one would kind of accidentally happen and then it would be that one for months). We were in school the day before 1/2 term started and we asked him to choose whether to come home with us or on the school bus (he chose us :) )
Understanding choice is quite a big one actually isn't it? I can see it will be very useful.
