Duo really is the best and they do make a waterproof version. The fact that she has no lashes to start with makes it tough for any kind of lashes to stick. Real lashes aid the glue in holding the false lashes on - so without them she's going to have a hard time keeping them on. I'd suggest she tries her hardest not to cry...
