We had an unexpectedly bright sunny day for our shoot. My go-to setup for shooting in sunlight is to shoot with the sun behind the subject and having a flash in the front to fill in the shadows on the face. I've literally used some variation of this for 40 years. The sun makes a nice hairlight/rimlight on the subject. But sometimes a regular flash struggles in this situation to have enough power to fill in the shadows. Fortunately I had my Godox AD200 super-flash along, with three times the power of a standard on-camera flash. Plenty of power to fill in the shadows, even at a distance.
Sheldon is also a photographer, in addition to being a model. I think this gives her an edge and helps our sessions to flow easily. Adalyn, meanwhile, is perfecting her "Diva Model" impression (which is actually pretty easy for a 2-year old).
