honey i wish i could help you more, but unfortunately my mum is not around to ask anymore.

All i can say is that my mother who was very petite and grew up as one of those "fragile" people, for lack of better words, who always fell sick at the drop of rain, or suffered nose bleeds at the first sign of physical exertion or hot days, well she developed severe arthritis age 25, then amazingly still went on from ages 38 to 42 give birth to us 3 children and raise us all without any home help. She did not have any c-sections either, we all were vaginal births, and the only pregnancy she has difficulties with was my youngest brother, where she was confined to bed rest in the last months, but i can tell you now, the only times she stopped housework was when she had migraines, no bed rest for her! She was an amazing woman and having the 3 of us in her condition was an amazing feat, and i'm sure you can do it too!

If you haven't already get in touch with the National Arthritis Foundation, they were a godsend of information for mum.
