I think Charlie might be most into Emmeline. He just wants to look at her and "pet" her and hold her. When she's crying he says things like "Don't worry Emmeline, I am right here." Or "don't cry little baby, I'm just leaving for a minute." He is always asking me "where is our baby?" and telling everyone "our baby is really cute."
He was excited on the second day when I put her in the little bassinet by my bed. He climbed up on the bed and said in a sincerely enthusiastic tone, "now I can put my cheeks like this and look at her."
