DS is 4 at the end of this month. For the last couple of months he has become increasingly obsessed with rainbows and all the colours of the rainbow. He recites them to himself and anyone who will listen all day from morning to night. He sorts his lego, pens, pencils, paintbrushes etc in to the rainbow colours and this goes on all day every day. We have tried painting, drawing rainbows, looking at books with rainbows in them. My dad bought him a prism so he could "make" rainbows himself. When we go to the greengrocer we look for fruit and veg for each of the colours of the rainbow.
To be honest, I'm finding it increasingly wearing and repetitive. Some days I feel my head will explode if I hear any more about rainbows! I'd love some ideas of things we could do together to give his passion for rainbows a bit more focus. Even his play leader at playgroup is at a loss.
Any ideas???
