I tried to avoid it but the kids would have been dissapointed so I've had to go. I've put my foot down with the swimming gala though - no way am I taking 3 year old twins to a swimming pool which they are not allowed into!
I think they prob woul;d be dissapointed if you didnt go, couldn't you jsut go a bit late? Ds1's was earlier this week and I saw him desperately looking for me before he spotted us, and his face lit up when he did see us. It does mean a lot to them.
