For the things he did when I was just a toddler : 

Daddy knew nothing about changing diapers, yet he did his best just for me to stop crying. When my hands were too small, he gave me two of his fingers so I had something to hold on to. He used to make me giggle by blowing bubbles or tickling me. He used to hold a stuffed toy in front of my face and speak in squeals voice for that look of wonder. Despite being a 'not so good photographer', I still remember how he used to take out his time to capture every moment.
