Josh looks at Kristin and then at their dad and says, "I think someone is getting tired."  He knows that it isn't his decision, but he also knows that it isn't like Gracie to hit people and scream.  He knows she is normally well behaved and that this means; normally that Gracie is tired.  He looks at Kristin and kisses her asking, "Do you want me to put her to bed?"  He looks back at the dad and says, "If you want Jack, I can do it."  He puts his hand around Kristin's hoping that her dad won't be mad at him.  He isn't trying to get rid of Gracie, but he does love Gracie and has been trying learn Gracie's sleeping schedule.
