At 37, many people are still getting to grips with being a parent. Matty Acton was learning how to be a grandparent. He and his wife Esther have two kids, aged 8 and 11, and he's also stepdad to Esther's 23 year old son Ethan - who became a dad himself last year. Esther and Matty, who's also a breakfast radio host on Brisbane's B105 radio station, have been documenting their journey on their podcast called Underaged Grandparents. In it they explore the unexpected challenges of becoming grandies while still navigating parenting, marriage and life in general. Matty also has well over 200-thousand followers on Facebook and Instagram, where he posts skits about daily life - like 'how to trick your kids into a confession', 'when mum has had enough', how house rules change when you have guests' and 'things parents of boys say...parts one and two.'
