I think anything can be a Daddy & little activity as long as you can maintain the dynamic through it... Daddy can be nurturing, guiding, teaching, discipling as well... I think cooking and eating together would make a good basis for a ddlb scene? From a writers point of view there's lots of different actions, and it has a natural progress: shopping, preping, cooking, eating, washing up... playing hide and seek in the supermarket, lb being told he's too little to use sharp knives and to keep away from the stove, daddy giving him something simple and safe to do to help, daddy helping little one to eat and wiping his face, daddy letting little one splash around with water and make bubbles with washing up liquid...
Now I wish I had a daddy who would make dinner with me :wub:
