Give it opportunities to grow.
Today I watched my daughter prance around the backyard acting like a deer. When she spied me, she ran behind some bushes to hide from the human. Later she came out and ran around the yard stopping every little bit to “eat” some grass (as pictured). She later sat down and had a rest while occasionally pawing at the ground with her “hooves”. I went back inside and she came to the door about 15 minutes later to show me a great stick that the deer had carried around. Suspicious, I asked her if she had actually carried the stick around in her mouth. Of course she had!
