Hi!
I live over at Nth Richmond & also have a 5yr old boy. I also have a 3yr old boy & 9 mth girl.
I don't attend any mothers groups but I am sure there are some around. Just depends on how far you wish to travel, the Hawkesbury is a big area.
My email is fionajill@bellybelly.com.au feel free to send me a email & maybe we will click & be able to meet up?

Oh & welcome to Belly Belly!

Fiona
