My boyfriends little 4 year old can obviously work her way around an ipad pretty dang good. I have put games on it for her when we are driving down the road and she needs something to do, but the little stinker has deleted/cleared my 3 pages of notes twice. I need to know how I can lock my apps so that she won't be able to access my important notes pages. Does anyone have any suggestions besides, not allowing her on my iPad in the first place!
