"Just a quick note to you my beautiful wife," the caption reads. "You are briefly napping on the other side of the room after being an amazing mom all night so you'll read this when you wake... seeing these images reminds me of those amazing 9 months that you sacrificed your whole being to grow our little one. The kindness, the beauty and organic nature of these photos makes me so very proud. You brought such fun and such power into our lives being pregnant but you literally brought the word sexy into pregnancy, we all see it. Thank you for being my partner in this life and thank you for inspiring not just me but all others who read, hear or see what your soul gives us. Love, You[r] husband."
