Just as a heads up the lounges are a dump at least they were last year. I visited the VIP lounge at the end of May 2014 as a then OWE and it awful. It was under some sort of renovation that was completely exposed to the open part of the lounge, the AC was barely working, and the internet was horrendously slow (when you could even connect).
If I were with a kid I would strongly consider hotel options because that lounge has a potential to get old fast (assuming they haven't improved it dramatically in the past 16 months.
