I know in the years to come they will fight like cats and dogs...but for now let me enjoy their friendship.
She loves him so much, he's the first person she asks about when she wakes up, she misses him at school (he's literally 20 feet away from her in the baby room), she is always playing with him and cuddling him. She often asks to make sure that he is going to live with us forever!
Grant loves Jenna just as much. He's constantly watching her and she can always get him to laugh and smile. He already looks up to her. She reads him books and he just sits and listens.
