I've been enjoying a neutral photo palette recently. I notice that my recommendations regarding What To Wear changes seasonally. Right now I like pale neutrals, with maybe a pop of spring color. Last summer, I was recommending jewel and garden tones. Fall - browns, creams, denim. Winter - festive red and classic colors like navy and white. Overall, it is fun to photograph saturated colors, but I think that subtle colors are best for showing off baby cuteness.
FYI, background is a bed with white linens. I photoshopped out the pillow creases/ edges in the background. Window light from the immediate right, umbrella electric continuous fill light from the left.
