Ok so I bought one of those belly support things because my back has been in a lot of pain. I've worn it for 2 hours so far and it feels good on my back but not my stomach, it felt kinda sore. So I took it off and as soon as I did Hanna started moving... could it be affecting her in any way? Has anyone ever used one and what are your thoughts on it?
