A warm flannelette nightie by the fire — soft, cheap, sold to every family as cosy and healthy. No one said it burned almost like gunpowder. A single spark at the hem reached the collar in fifteen seconds, and children died in their own bedclothes for decades. A flame-resistant version had existed since 1910 — yet ordinary flannelette stayed on sale for children for another fifty years. Coroner after coroner demanded action. Finally, in 1964, Britain banned it. The warnings came too late for thousands. But the law their deaths forced has kept children safe ever since. Share this for the children it saved. #BritishHistory #HiddenHistory #SocialHistory #UKHistory #ForgottenHistory
