Hi Jayfer and congratulations on your first baby .
I have RA too and am pregnant with my second DC. I only developed RA six months after having my DD and it was under control wih sulphasalazine within six months. I'm off my medication now as my joints seem to be fine in pregnancy, but am worried about a flare after DC2 arrives.
Really sorry to hear that you're so worried about labour and afterwards. How far along are you and what does your normal MW advise? Are you going to be able to see your normal midwife and write out a detailed birth plan taking into account how to conserve energy and what will happen if you do become too tired? If you're going to antentatal classes the teacher may be able to give you some tailored advice too.
As for after the birth, I've had some basic information from Arthritis Research UK www.arthritisresearchuk.org/arthritis_information/arthritis_and_daily_life/pregnancy_and_arthritis.a spx mainly around the drugs side of things. I'm also seeing my rheumatologist next month to talk about breastfeeding and drugs following the birth.
I know that for you things are more complicated as you also have Fibro - if you haven't already, can you talk to your consultant perhaps?
If you're having a hospital birth, when you're on the postnatal ward I'd hope that you'd be well looked after and helped with your baby. It's worth asking for help upfront though and to keep asking as the ward can get rather hectic.
As for being at home after the birth, do you have a partner, family or friends that will be able to help you out? And/or could Sure Start volunteers help?
New babys are hard work but with the right support you'll find ways to work around feeding, changing, dressing etc that will make life easier. Good luck and I hope that all goes well
