Finding the "Catch Light"

I just joined a great photography club and feel so lucky to have this forum where I get together with a bunch of mother's who all have the same interest: taking better pictures (especially of their kids!). We had a wonderful guest speaker last night, local Seattle photographer- Janet Klinger who talked about the importance of "finding the catch light". I had gone over this with Mimi a few weeks ago, but it was great to get more practice! We had the opportunity to shoot a member's darling newborn for practice. Lauren was adorable and a wonderful sport. Today I tried to get Megan in the position where I could find the perfect light- I have posted a few of my attempts.
