Ds is nearly 4 and for ages now if you ask him to say pick something up off the floor, he takes ages to find it, even if it is really obviously right next to him. It doesn't always happen but the majority of the time it does.
I can't work out wether it could be a) A heraing prob, b) an eyesight prob, or c) that he just isn't following my instructions very well.
Would be surprised if it is A because he can always hear perfectly well when he wants too.
Any ideas ??
