Song for a MOTHER and a SON?

My cousin just had a little boy named Michael. And she had a daughter before him named Hailey and she has a song for her called In My Daughter's Eyes by Martina McBride. I was wondering if anyone could give me some sentimental songs like that for little Michael and his Mom. Please not for a father and a son, because the Father isn't involved. And I know some good ones of those anyway, like Watching You by Rodney Atkins. Thank you. :)
