Thanks Melissa for the explanation. Georgie's right hip is at 67% coverage and left 72% which has been deemed normal. It is interesting the different approaches. Your Dr allowed only night time usage when at 67% whereas ours has said all sleeps. Mind you we are only giving her 10-15 mins each time she is awake out of it plus bath time just coz it is easier (I find it a hassle to take the harness on and off given clothes need to come on and off). I figure it is not doing her any damage being it in during the day and perhaps can even ensure our best chance of getting her out of it completely within the next 6 weeks.
