dear Fiona,
Being a mum I understand your worry.
Is it your first?
Iīm afraid I have to agree with the other health professionals, every fracture takes 6 weeks to heal and an elbow fracture ( with surgery) is not the easiest of fractures. In my experience it normally takes time to get back the rotation movement( palm up- palm down) even after the fracture has healed. Be careful of aggrevating exersises! pain is a useful signal.

Now the good news.
I have seen mums with one arm only! or in a wheelchair nurse their children.
It is amazing how adaptable you can be when necessary. I presume you will have help around ( husband, family and friends) so let them help you.
I couldnīt look after( bath and clothe) my own (1st) child because of maternal complications after traumatic childbirth for nearly 2 weeks and its was a bummer.... but... I could still feed him. Accepting help and enjoying everyone helping you is not too bad you know! In the first few weeks, a child sleeps a lot, giving you time to heal. My advice to you is to take that time.

I wish you and yours the best of luck and enjoy what you do have .........
Esther
