You may be overanalyzing this shot too much. You have a closeup here of a little one and your practicing for shots that wont be close ups (mostly) and wont be of little ones. Step back a bit and see if you can get a few people to help you out and model for you. You will need to analyse those shots more than this one.
Try Shutter priority or Program modes with a TTL flash. Keep it under 1/200th. If you need to, tell your flash to overexpose just a tad.
