This PSA always leaves a very warm uplifted smile on my face, and I know many others who also experience this. We did it also as part of the YOU Campaign. Here we have kids talking their own baby talk and understanding each other, in fact talking to their HIV positive parents about what they would want... to stay alive (PMCTC). It is always the most challenging to work with kids, babies even worse, and casting becomes the saviour, as it was in this PSA too. These babies really "killed" their performances.
