I think you need to find someone to handle the feeding, dusting, changing of water, misting... welcome to frog keeping!
But seriously, I went away for 4 days once and my husband comlpletely forgot to feed my frogs and change the water bowl (I did have a repti fogger set up, so the humidity and temps were fine)! Needless to say, my hubby had a lot of making up to do
My white's were just fine, but hungry! So Bill is right, if well fed, they can go a while with out food. but white's are plumper than your little one, so a week may be a stretch.
