DD1 never used to be but after he had time off at X-Mas and then when i went into hosp for DD2 she is now.
We say Daddy's home and she runs to 1 door (glass, sliding, she can see up the drive then) and then when he stops she runs to the other door and yells DADDY and bangs on the door til he looks at her!

She also pretends to talk on the phone now and every time it's always Dad or Daddy and she YELLS his name.

I agree though it's great to see the bond there, DP used to feel a bit frustrated i think because we spent all day together and he worked long hours and she would choose me over him.. now she doesn't care who puts her to bed etc and is more than happy to have Daddy cuddles.
