I'm with Anthony on this one. I'm interested to know of the outcome of this case though. Sounds like they would be better suing for negligence and injury to feelings/psychological injury, but not ptsd. Apart from the fact that having tried so long for a baby, it's hardly surprising that the mother is super-anxious about losing it, regardless of the mix up or not. Fathers generally don't tend to have the same level of protective feelings as mother's (note I say "generally" here, before the forum is filled with insulted fathers!), so maybe that's why the partner is so pissed off, because his other half is concentrating on the baby and not him!
