The program is Canadian and just started up in Australia, and Victoria, this year!
You and your baby / child go along for an hour and sing songs and rhymes. You learn some new ones too and remember some from your childhood you might have forgotton. They tell and teach stories too.
Then you get to socialise with other parents and their children while being waited upon with a snack and cuppa.
Keep an eye out in your area. My local paper had one advertised but sometimes you might just have to ask your Maternal Child Health Nurse and local shops etc.
