Moleskins, whats the old coke bottle for?
Sally
If you dont want to buy a dedicated lamb bottle then you buy either a pritchards teat or pull-on teat and these fit onto the 2 Litre coke bottles (or lemonade etc)
Since the thread is underway then also consider:
Prolapse spoon / Truss - In case of prolapse pre or post lambing
Lamb puller - For difficult births when you simply cant get a grip.
Lamb adoption musk - for adopting lambs onto other ewes
Needles + sutcheres
etc etc - as I said the list is endless, unless you decide up front how much you are prepared to do before calling assistance from a vet or experienced sheep owner.
