We started the pump (saline) at end of April, almost 7 months ago to the day and she's only let us use her bottom. She let us try a thigh site tonight!!! She said no stinging occurred like it does on her bottom, and it didn't even hurt! I'm doing a dance, I wish you could see! It took $5.00 out of my wallet, and putting the Christmas tree up tonight- a small price to pay in my opinion.
