Our two year old as gotten quite attached to her baby doll. She mothers her in all sorts of ways.
She reads her stories at nap time.
And arranges a spot for her (and almost every one of her stuffed animals) to sleep beside her at nap time.
She gives her a nebulizer treatment because she had a bad cough.
She even started potty training her this week!
I must say I am enjoying watching her in this stage.
