The past couple months have been pretty tense, Skeezix-wise, as the prospect of pre-term labor has been with us pretty constantly. But the Adorable Progeny has hung in so far, and every day he does he gets stronger and more developed. So listen to your father, Skeezix, and stay put for another ten weeks, okay?
The line quoted is from Sea Dreams by Alfred, Lord Tennyson. Sea Dreams is a narrative poem about a family coping with getting swindled out of their savings, but the following is often excerpted as Cradle Song for collections of children's poetry:
What does the little birdie say
In her nest at peep of day?
Let me fly, says little birdie,
Mother, let me fly away.
Birdie, rest a little longer,
Till the little wings are stronger.
So she rests a little longer,
Then she flies away.
What does little baby say,
In her bed at peep of day?
Baby says, like little birdie,
Let me rise and fly away.
Baby, sleep a little longer,
Till the little limbs are stronger.
If she sleeps a little longer,
Baby too shall fly away.
