The Process of Lambing

Just watch, and RESIST the urge to "do something" to help.
There's no rushing them, and disturbing them will slow it down.
Only after her water breaks is the time that she's should show continous progression.
When you first start to see the lamb, make sure youre seeing 2 hooves and a nose.
If you are, things are fine.
If not, then it may be time to wash up and feel inside to see how the lamb is positioned.
The vast majority of ewes get by with no help at all.
Let HER clean the lamb, and get them into a small dry, draft free pen for a couple of days to bond.
Clip the cord and dip or spray with iodine, milk the ewe enough to make sure the colostrum is flowing and the teats arent blocked, and make sure the lamb nurses within the first hour.
She wont be nearly as nervous about it as you will be
Good luck!
