Nine days and counting

Yes nine days til I make a road trip with my mom and neice to see Rowan the Red party his diaper off. I'm really pretty excited to see my neice for an extended period of time and then my nephews that are still small enough to spoil and love and cuddle.I'm packing clothes that don't stain-looking into some new running/walking shoes(toddlers tend to be incredibly quick) and in general staying well.How old do kids have to be before they get their own sound system? Maybe something a little quieter-that doesn't eat or poop.
