Happy Father's Day to the most perfect man Luna and I could ever ask for. Since the day she was born, you've done every bottle with me, woken up with me to keep me company through every night. You don't mind diapers, get all the best burps, and read her Goodnight Moon like poetry. It makes me so happy to see so much of you in her smile and eyes that completely glow when looking at you. She will never look at anyone - anyone - the way she looks at you...
