First, I purchased a shoulder posture support brace that is basically like a racer-back bra without the bar part. It can be worn under clothes or over the top. I don't wear it everyday but on days when I'm around the house doing a lot of bending and cleaning or just on my feet a lot, I like to wear this. It holds my shoulders back and allows me to breath better. My chiropractor warned me not to wear it all the time or the back muscles will relax and rely on its support. But mostly, it has helped me maintain better posture as my belly grows and adds more of a strain on me. Presently, I have only gone to the chiropractor twice in my pregnancy and not for pain but general maintenance. The brace I have is shown below (I snagged it on sale around the holidays.):
Taking this time to open my body and also wake up in this gradual manner has been a great way to start my day. I kinda wish I would have started it before this pregnancy, as it would have helped me be more patient in the morning with my kids. But now it has finally become routine. I'm starting my day on my terms, even though it is such a short period of time.
