I've had a fairly steady routine script at bedtime for the last 3 years or so. After Caitlyn's lullabies, I say, "Sweet dreams. Mama loves you. See you in the morning." For quite some time now, Caitlyn has repeated each sentence back to me in a bedtime call and response sort of thing.

Tonight's version went like this:

Me: Sweet dreams.
Her: Sweet dreams.
Me: See you in the morning. Mama loves you.
Her: Mama loves you. I mean, Caitlyn loves you.

She's just shy of four and one-half. This is the first time she's changed the subject of that sentence. Makes a mama's heart go all mushy.
