Hi Amy,
First I wanted to say thank-you so much for your DR blog posts (I felt quite alone before reading them) followed by setting up this forum for us all to share our DR journeys with each other. You have comforted and inspired me, and I have started the Julie Tupler Diastasis Rehab program today.
The appearance of my DR is quite similar to yours in the side-on profile shots (although when I measure it is only 3 fingers), but I have only had 1 baby, who is now 2. I suspect that I had DR well before my pregnancy, and just didn't know it (tummy was never flat even though I was slim everywhere else, my back always had an extremely pronounced arch towards the front). Also, my first pregnancy, in a very slim, fit and strong body (I was a runner and rockclimber, and extremely slim and fit when I fell pregnant), showed very early, and only ever grew straight out from my belly (I now suspect more like "fell out"). I experienced severe pelvic pain from 5 months onwards, which at least made me wear a kind of support splint that went under the belly, so that the pain didn't entirely prevent me from walking. My pregnant belly was so hugely sticking out the front, that experienced midwives assumed from my appearance that I was carrying twins, before my EDD.
Anyway, onto the DR rehab program. I have committed myself to sticking with it for 6wks, but it is very tough, right from the start. I am just not physically able to do all the things the program asks in week 1. I know that just means that my transverse is weak, and that by doing all that I can it will get stronger and improve my ability to perform the 4 steps over time. But it still feels quite disheartening. Time to accept that emotion is there and to do the actions anyway, to the best of my ability. I hope that by sharing I can encourage others who may feel the same, and that it will also give me some added motivation to stick with it.
Wishing you all the best as we share this challenging process towards better health.
