Thanks everyone Guess I will just have to wait and see if they get over it...lol At least they are 6 hours drive away, so it's not like we have to see them all that often.
And in a strange way, I think it will make me a better parent too, I kind of know what not to do! I understand it must be a shock for them, but having kids is sort of the next logical step, I know I would much rather be a younger grandparent if I was in their shoes (not that they are even old, but it's not like they are going to be 70 or 80 and being unable to play with them...). I guess the next 7 months will tell!

Thanks again for all your lovely words, it really does make a difference when you know that others have also experienced what you have, and that there is lots of support out there (even if it doesn't always come in parental form! Lol).
