Inevitably the baby knows when you truly settled in to sleep.
You stop reading your book, you roll to your side or forget to keep obsessively thinking and listening for her sounds.
She knows, she wakes, she cries (oh the crying!), she pleads for a body besides hers, and probably not brothers, to be resting on.
The heaviness of rising and walking amidst the nighttime obstacle course of clothes, toys, books and cats.
Oh the crying, never is the illogical musings of a baby more irritating than when your mind wants to stop.
