I have been very busy so here is a quick session I did the other day. When working with kids, especially young kids, give them something to explore. In this case, I gave her some of my juggling gear. Generally, the more they can pick the items up and look at them from different angles the better it will work out for you. Within reason though, obviously I am not giving her my juggling machetes or juggling torches. Use your best judgement.
This shot was done with just two lights. The key light was just off to the side and equipped with a softbox that had a grid attached. The hair light was up above and had a snoot with a grid on. The trick with snoots and two year olds is that two year olds move around and snoots tend to cover a narrow area. So, keep your subject in mind when using a snoot.
