Alex says I'm his life

Alex is such a little sweetheart and this is a memory I hope I have forever! He loves to argue and is always hugging me and telling Marc " she's my Nana" and Marc will say "no she's mine". A week or so ago they were doing that and Marc said "she's my wife" and Alex said "no, she's my life"! I told Marc that Alex had won that one and he couldn't top it with any saying. Alex is always saying you're my life Nana or he will ask me "are you my life?" And my answer is yes I am!
