Mum describes difficulty of breastfeeding tongue-tied baby

When my youngest child was born five years ago, I found breastfeeding very painful and difficult. If he’d been my first child, I would have assumed that the pain was standard. But he was my third, and I knew there was something wrong.
When he was a week old, after much pain and many tears, I discovered he had tongue tie, a condition whereby the piece of tissue (frenulum) under a baby’s tongue is too tight.
