Hi Kylie, welcome to BB
A couple of girls and I meet up every monday at my church at Thornleigh for 'playgroup', which is really just a cuppa or a walk or something, and a chat LOL. You'd be more than welcome to join us Its probably about 15mins drive from Castle Hill.
My DD is the oldest, at 15 months, but the other babies are 3 and 5 months old.
Let me know if you'd like more details!
