Surprised - I thought I would update. DD3 is getting her lip tie released by laser this Saturday by a dentist here in Newcastle. It is going to cost $180, so much cheaper than the dentist in Sydney. They do tongue tie and lip tie release from days old, so there is no age limit. Like a TT release, it will only take a couple of seconds and is pain free because of the laser.

I'm not sure which area you're in but perhaps google laser dentists or laser dentistry in your area and give some a call.
