Creative development can be drawing, painting, role play, using one object to represent another, singing, making up games, experimenting with sounds (musical or verbal).
so.. i child might say "oh no there's a monster coming, run!" , "I'm going to use red now",
"now you be the baby and I'll be the mummy",
"Sit there and I'll cook you some dinner",
"I saw a butterfly with pink squares on it and it said hello to me",
(if they have drawn or "written") "this is a picture of....." even if the picture is of a blob.
They might write some letters and read it back as a sentence.
"don't fall off the block or the sharks will eat you!"
Hope this helps, can you spend a day in a preschool environment and write down examples of what they say?
