My 8yr/o peed to bed last week and again last night she has no burning when pee but says she can't empty her bladder all the way any suggestions?

See her doctor: She may have a urinary infection or bladder irritation. New bedwetting can be a sign of a UTI even without pain on urination. See the doctor to get her checked.

See Your Doctor Now: The classical symptoms of bladder infection are pain/burning, frequent urination, incontinence, & abdominal pain. Children have limited communication skills; cues indicating symptoms are easily missed. The combination of urinary incontinence w/ incomplete voiding (can be due to discomfort during urination) suggests possible urinary tract infection. See doctor now for prompt diagnosis & treatment
