The tongue tie was released, as was the frenulum under the centre of his upper lip which was also too tight, and Charlie had a breast-feed within minutes.
"I felt instantly better," said Mrs Andrews. "It was still painful because I had so much damage there. Within a week my nipples started to heal."
Parents are being urged to shop around if their baby needs tongue tie treatment for which the fees can range from $880 at Laser LifeCare, to typically $150 to $200 - and just $25 for enrolled patients at Turuki Health Care in Mangere.
Mrs Andrews said the Laser LifeCare fee was money well spent.
"It's really hard being a mum and not being able to feed your baby because you feel like you're not doing your job properly. There's a lot of pressure to breast feed and you really want to do your best to breast feed and you still feel like a failure even though it's beyond your control."
Laser LifeCare owner Dr Hisham Abdalla, a dentist, said his fee was not excessive. Treating a tongue tie in hospital, under general anaesthetic, cost a great deal more.
Auckland GP Dr Yvonne LeFort said one study had found that 40 per cent of mothers with breast-feeding problems had a baby with a tongue tie. She charges around $150 to release a straightforward tongue tie with a snip using surgical scissors, done with anaesthetic gel and without stitches.
Hamilton oral and maxillofacial surgeon Steven Evans charges $180 for the laser treatment.
The city's Old Villa Dental clinic charges $198 for water-laser treatment of tongue tie and reports having treated many Aucklanders.
