Hi! I would say welcome to BB, but I see you've been here for a while

I'm Liz, 25 and from Baldivis, which is 10 minutes away from Rockingham. I personally dunno about playgroups around Rockingham, but if you contact the Ameer St Child Health Nurse, I'm sure they'll be able to give you as much information as they can give you.
Also, Google is your friend
