I spoke to someone who had heard it and then googled 'nappy expo' and got the information from Helens Aquabubs site.
How wonderful that the NZ Herald at least picked up on the Expo. I suspect you will find that they are NOT ALLOWED to mention the exact location as that would be FREE advertising. Got to keep it fair for all.
Glad to hear that some new parents were using modern resources to 'come - see' and there were lots of wonderful -1st time - round tummies there yesterday and it was really great to see. Great effort by all and great to see so many supporting the Expo. It is very exciting and I personally felt there were far more parents interested in cloth nappies this year.
If any Auckland people would like to follow through with another article in the NZ Herald or local papers, please contact me for photos!
