Maya (2yo) just told me the best story ever.
According to her, the reason she wakes up every night is that a bunch of hungry lemons come knocking on her door. Obviously, she has to wake up and cook dinner for them (they like salmon, apparently).
When they’re done eating, a banana turns up and takes the lemons back home.
As a sign of gratitude, the lemons leave her a gift (usually a toy) the morning after.
