I just wanted to share my experience. My baby had a lip and posterior tongue tie. She is now 7 weeks old. We've been to a lactation consultation 3 times since she was born. We thought maybe it was her latch causing me pain. When we discovered it was her ties we made an appointment with a pediatric dentist. He decided that they were bad enough to be corrected. He laser cut them. Since her procedure she can keep a paci in her mouth. She nurses like a champ and I have NO PAIN! 👍🏼 She also has no gas and is not colicky. It made a complete difference. She's so much happy and things are going great now!
