DD1, age 3.5, has always been a good sleeper.
But lately she's waking once or twice between 10PM-midnight, or sometimes in the night, calling out for a drink of water or a particular cuddly, etc.
Then she says, when you give it to her, 'I need to sleep.'
And off she goes again.
WTF?
DH thinks it might be b/c she's checking to see if we're still here.
