Kirstie Andrews' introduction to breastfeeding her newborn son Charlie was marred by a tiny deformity under his tongue - until he had an operation that cost more than $800.
The Auckland mother suffered bleeding and severe pain in her nipples, and three infections requiring antibiotics - all because of tongue tie, a condition which affects up to 11 per cent of infants.
"For five weeks I was struggling. It was getting worse and worse and worse."
Charlie's milk intake was not affected by his inability to latch on properly and he put on "heaps of weight", although his feeds went on for 60 to 90 minutes at a time because they were so inefficient.
After the problem was diagnosed, the too-tight tissue, called the tongue frenulum, was surgically snipped, but that didn't help and Charlie, now aged 1, was taken for laser treatment at the Laser LifeCare Institute, a dental clinic in Auckland.
