(Portland, OR)  --  Police say they've arrested a 22-year-old woman after she left her two-year-old child alone in a tent.  Authorities say 22-year-old Taylor Marie Kuhn was found Friday, sleeping in a car in the back yard of her home on North James Street with a meth pipe in her shirt.  Police say after the toddler was found, wearing only thin pajamas and a wet diaper, Kuhn admitted the child may have been in the tent for about five hours.  The toddler was taken to Randall Children's Hospital.
