I have been in this field for close to 15 years. I came across your website initially because I was searching for a shared, personal forum with other professionals in my field that was not attached to random advertising and monthly fees. After discovering your website which hosted a forum that was exactly what I was looking for, as well as providing a mountain of resources that didn’t require you to follow several external links to get to, and to top it off no monthly recurring fee...Jackpot!
Golden Carers also has a ton of fun resources here https://www.goldencarers.com/calendar/grandparents-day-australia-activities/78/.
I would love to hear what you come up with!
