Congrats to you!!
I also used my vest right up to the end- during early labor. I wanted to get a treatment in right before heading to the hospital because I knew it could be a while until I got my next one! I'm glad I did because boy was labor a lot of work! I actively pushed for about 3 hours and nobody (including myself) could believe how well I handled it (breathing and lung-wise).
Earlier in my pregnancy I called Hill-rom and they sent me a disposable chest wrap vest. I ended up never using it. As others have said, I just loosened the straps and the vest rode up as I got bigger. Ended up not being an issue at all, which I was sure it would be. You could go ahead and call Hill-rom to get the wrap just in case. It was a super simple phone call and they send it no charge.
Marisa, that is too funny about your hubby! Mostly because my husband and I were worried about it as well. We asked my CF doc are you SURE it can't hurt the baby or cause shaken baby syndrome??
One thing no one warned me about was how badly it would hurt to cough afterward. In retrospect it seems like something I should have thought of! I was only worried about how hard it would be to cough/vest if I had to have a c-section but it never really crossed my mind for a vaginal delivery! It took a solid week before it didn't hurt terribly to cough. Sorry if TMI but I also needed stitches so I had to try to suppress my cough somewhat because in addition to hurting each time I did I felt like I was going to pull a stitch. Sorry, not trying to scare you, just saying make sure you are getting good treatments/CPT right up till the end because afterwards your treatments will be a little lacking for a while.
Good luck you and take care!
