Many congratulations to you and your partner. How exciting 3 bundles of joy. Someone mentioned multiple births assoc, just google it for au sites only or enter triplets and I am sure you will find heaps of sites. I think you can hire triplet prams and things like that aswell. As far as I know when you get the payment for the gov you get it x3 plus a bonus for having more than 2. Not 100% sure on this but it sounds good.
All the best with ms and finding clothes etc, take it easy.

Love
