Flat Beach Slate Jizo Bodhisattva with Lotus Flower by LillaJizo. Jizo is a Japanese Buddhist deity that is believed to protect travellers, children, pregnant women, and - most importantly - those children who died before they could be born.
These remind me of mandalas. We could get stones and do mandala zendoodle art on them, and then write a simple encouraging message on the back for baby girl. Make a nice fabric bag for her to keep them in.
