Time for you to sleep

How do we learn to be mothers? There is a instinct inside us, we are just another part of the animal kingdom. And then there is the part of experience. Quantum science says you can only know what you have experienced.
I have witnessed this theory many times since having Lila. The song I sing because it was sung to me. (Jeff had a very similar experience with a Christmas tune)
I wonder will Lila sing "night night" to her babies? She already does!
