My children grew up in Wales. Dressing up on St David's Day was mandatory, babies too, wearing Welsh bonnets and shawls. The boys wore little leeks, which they nibbled during the school day.
They always learned Welsh songs and when I asked, "What does it mean in English?" they looked blank.
I'm afraid I never embraced Welsh culture as I lived in a horrible dump with a horrible husband. I escaped after 22 years and have never been back but am sorry now for all that I missed.
