Mmmmm, too many old wives tales there for me sorry. My skin isn't that elastic at all - I get horrible stretchies, yet I have had one accidental pg, and 3 conceived first try. I have an average size shoe yet pushed out one large (going by his standards a baby under 9lb s large), 2 super size ones and one super-super size one. I know of a lot of islander women who have absolute whopper size babies. I reckon you could *work* on the theory of a shorter birth because second labours are often shorter anyway.

At the end of the day though, what is important is that you love him and you trust him.
