i figure the same thing BW - how do you know if it's the IVF conception or the physical reason that the parents needs the IVF that causes these changes that they report

in my mind, the chances of having a smaller bubba just cos it's conceived via IVF is in no way going to change the fact that we'll pursue IVF if we need to! if you've gone through IVF, you obviously really want to have a child, so their birthweight isn't going to be important!
