DD is an articulate 3.5 years and still only understands pointing because she can sometimes understand the instructions which go with it. (eg "Look in the direction of mummy's finger and where mummy would be looking now. If you were here what would you see?" etc) I've tried to turn it into a game for practice, which she sort of understands, but she doesn't really understand it as more than that (so she'll strike up the game with me, but not use pointing as a tool).
Is this odd? Go on - humour me! (I only have DS to compare to and he's been pointing since 10m.)
(She has other oddities too, but this is beginning to seem to a bit of a gap in her abilities.)
