At first, he was very very serious. I noticed that he often fixed his eyes on his blue fish-shaped teething toy. So with my left hand, I swooped the fish around, while saying "WHOOOOSH!" in a really theatrical way.
Simple white onesies are great for baby shoots. Flattering on all babies. Also good for natural light photography, because light reflects off it, and helps to light places like under the chin, nose and brows. I also like to photograph knit items on babies. The textured yarn emphasizes the smoothness of baby skin.
These were taken at 1:30pm, which is in my least favorite window of time to photograph. The diffuse lighting in the shade was wonderful however!
