Thanks guys. I am planning to say pretty much that. And it may not be such a big deal to them anyway. But the older girls do understand these things alot better than the younger ones & they may be upset. They aren't really at the age where they can see the difference between an early embryo & a new born baby that was their brother or sister they were excited about.

I've never been there & I don't have anyone close to me who has either. So its not something they've ever heard about to know that it does happen.

When he told them they didn't even say anything to me when they got home. Just asked to go in the pool & that was that. So it might just get the same reaction.
