It'll be 30hrs for 9 months old from September 2025 but for yours it'll be the term after so January 2026! It's always the start of the first term after they hit the age.
My girl was march 2022 and she got 15 free hours April 2024.
You get 15 hours from 9 months, but the hours don’t start until a term starts (September and January), so it won’t be until January 2026 for March babies 😖
