If you shot the picture RAW you should be able to get some more detail out of that slightly annoying highlight on the baby's head and still bring up the father's face a little more with a little post-processing. Or send me the RAW and I'll give it a shot - I'm playing with the Aperture 2 trial version which is rather a nice toy.
I found some good deals on memory cards online. The price has come down a fair bit over the last 18 months. Ad astra per aspera
