I love you, Mommy!

Tonight, as Ryan was cuddling with me on the couch in the basement, he said 'I love you, Mommy'. He has said this before...but it still floods my heart everytime I hear it. He didn't even look up at me. He spoke the words, knowing I would hear them and respond. Of course, big sis bounded over 2 seconds later and said 'I love you too, Mommy'. How did I get so lucky?
