Should we go through with the surgery? Rosie is only 6!?

If it is a cochlear implant you are talking about then I would seriously consider it. A cochlear implant could make a huge difference to your daughter. Find out as much as you can by talking with your doctor then make a decision based on the information you have and what you feel would be right for Rosie. My father has a cochlear implant and it has changed his life for the better. While his hearing isn't perfect he is now able to sit down and have a conversation with somebody, something that was previously becoming impossible.
