How to react?

Yesterday, I was seated on a sofa, nearly falling asleep. Chloe suddenly came up to me, pointed at my tummy and said, "Baby."

I was then awakened by what Chloe said. Next moment, she lifted my top slightly and kissed my tummy. Her tiny hand stroke my tummy while saying "Saiyang.." All these little acts were what we taught her when I was still expecting Caleb. This reminded me the day before I induced Caleb, she did exactly the same thing.

Looking at her innocent expression, I was instantly at a loss. How am I supposed to react? It has been 2 months plus since my tummy "disappeared". Is she still expecting a baby brother to join our family? What should I say to her? What can I say to her?

Practically nothing..
