The challenging thing about newborn photography is that it's always changing. Babies are different. Their sleeping times are different. Lighting and space are different at each home (since I travel to newborn's place to shoot). So I cannot follow a specific plan as in engagement shoots. So the flow ended up different at each shot no matter how much I pre-visualized.
The similarity is the end result that always make me smile with super cute babies. If I'm loving those cute baby photos this much, no words I can use to describe their parents. And it's so rewarding that keeps me wanting to do newborn photography.
