I lost my dad on 1/1 and the last week or so I cant get him off my mind.

My dad was particularly close to my youngest DD who is only 23 months. She "asked" for him all the time after his passing. Everytime the door opened she would call for him thinking it was him. I realized yesterday that she hasn't asked for him for quite a few weeks now.. I guess she has forgotten him or realized that he isn't around anymore.. the thought of this made me break down in tears.
