T1000, great to hear about your fantastic weekend. I thought I had replied about your sons birthday situation, but cannot see it. My two cents worth: at this age the kids don't really worry too much about when the day of birthday is being celebrated, as long as it is celebrated. Therefore simply have a great party for your son when it is your weekend, he will still appreciate it.
