Early Mommy Training

I found a tiny baby doll in Breanna's shirt while she played in her room. I thought she was being silly since she likes stuffing toys down her shirt for the sensorial experience or to just have pride in hiding "treasures". Curious, I asked what it was doing there. She told me that the baby is in her belly and the doctor has to take it out. What an influence I am! I'm wondering if she's recognising the change of my growing belly?
