You need to call the doctor, antibiotics should have kicked in within 24 hours. It sounds like this antibiotic she was given doesn't work to kill the bug she has. That actually happens often and it should be easy for the doctor to switch her to a different antibiotic.
Does he have her on any pain medications? There is one that is just for bladder infections, pyridium. It will turn her urine orange but it numbs the bladder.
Make sure she is drinking a LOT of water. If she is refusing to take it (I see she is only 20 months) then you need to get her to the doctor for IV fluids.
