Lately, Isabelle's independance has been peaking. If she doesn't get something she wants, she'll scream, do the back arch, and then put her little finger in your face and say, "No!" My first reaction is to laugh...especially when she's doing it to her Daddy, and I'm just an innocent by stander.
But we both push the laugher down and proceed with responsible course of correction. I'm thinking of inviting the Miller's new family friend, Sad Man, to our house soon.
