Katfish - Sorry but didn't have that problem with DD1, she would be red behind her knees but that was it. Rest assured she will sleep again, within a couple of days she will settled down. Can I ask where you are? Who fitted the harness are you due to go back to have it checked next week? We had an app with our Orthatist 3-4 days after the inital fitting to ensure there was no rubbing and that we were coping.
