but with sheep you have to watch out for lambs being stolen by another, not-quite-ready-to-pop ewe, while the other one is having the twin/triplet... not sure if pigs do the same. thats why being present with lambs is so important. I had two ewes producing 5 between them early one morning last year - it was a bit of a scramble to sort out who's was who's....
all the best for the piglets.
have you had your three cups of tea/coffee yet? I was told it takes 3 months, 3 weeks, 3 days and (at least) 3 cups of tea before farrowing....
