Many times when my kids were small we would find ourselves in a park, hotel, restaurant or airplane when suddenly they would need a simple prop for pretending.
Our dear friend Torii most often requested a baby. I got good at wrapping up a playsilk in such a way that she could cradle it, love it and imagine it was her real baby.
My sons more often wanted an animal, or a throwing toy. We learned to tie silks into little animals for floor play and shooting stars to throw in hotel rooms.
