Protection is also likely to be a theme. Dadzawa would probably be in a position to protect baby Izuku from harm, and this could be a central part of the story, showing Dadzawa's role as a protector and Izuku's need for that protection.
A common theme could be growth. As Izuku is a baby, we can expect to see his growth over time, whether it's physical, mental or in terms of his abilities, with Dadzawa playing a role in it.
Another theme might be family. Even if not a biological family, the relationship between Dadzawa and baby Izuku can be seen as a form of family, with all the love, care and support that comes with it.
