Holly is in love with her new baby brother! She adores him, wants to hold him, sings to him daily, reads to him daily, asks to kiss & snuggle him and is always trying to make him laugh... which lately is the *thing* to do since he loves to smile and laugh!
And, on that same note when Hudson realizes Holly is around he *cannot* keep his eyes off of her. He will crank his head in all directions and arch his back to locate her. In the car he sits in his car seat and just watches her smiling the whole time. I'd say he too is in love with his big sister!
