As a parent, nothing feels more important than making sure your baby is feeding well and gaining weight as expected. But what happens when things don’t go as planned? If your baby struggles during feedings, cries frequently, or isn’t gaining weight steadily, one lesser-known cause could be a tongue tie or lip tie. These conditions are more common than most parents realize and can significantly affect your baby’s ability to feed effectively—directly impacting weight gain and overall growth.
In this guide, we’ll walk you through how a tongue tied baby can experience feeding challenges, how it affects weight gain, and what steps you can take to help your baby thrive—literally.
What Is a Tongue Tie?
A tongue tie, medically known as ankyloglossia, is when the thin piece of tissue (called the lingual frenulum) that connects the tongue to the bottom of the mouth is unusually tight, thick, or short. This restricts how well the tongue can move.
Similarly, a lip tie occurs when the upper lip is tightly tethered to the gum, limiting the lip’s ability to flange outward, which is important for creating a proper seal during breastfeeding or bottle feeding.
Together, tongue and lip ties can create major feeding challenges in infants—especially during the crucial early months when steady weight gain is essential.
How Does Tongue Tie Affect Feeding and Weight Gain?
Feeding isn’t just about nutrition—it’s about connection, bonding, and growth. But a tongue tied baby can face the following issues that impact feeding:
1. Poor Latch During Breastfeeding
Babies with tongue or lip ties may have difficulty forming a strong latch. This leads to inefficient milk transfer, longer feeds, or a frustrated baby who tires out before getting full. Mothers often experience pain, sore nipples, or even mastitis as a result.
2. Short and Frequent Feeding Sessions
Due to inefficient sucking, these babies often nurse frequently but don’t gain enough. You may notice your baby feeding for short periods and then acting hungry again soon after.
3. Swallowing Air and Digestive Discomfort
Improper latch can cause excess air swallowing, leading to colic-like symptoms, gassiness, or reflux—all of which can impact comfort during feedings.
4. Slow or Inadequate Weight Gain
When babies aren’t able to transfer enough milk per feeding, it shows up on the growth chart. Some parents may hear that their baby is “failing to thrive”—a scary but solvable issue when tongue tie is the underlying cause.
Signs Your Baby Might Be Affected
Wondering if a tongue or lip tie might be the root of your baby’s feeding problems? Here are some common signs:
- Clicking sounds while feeding
- Baby frequently unlatches or pulls away
- Long or stressful feeding sessions
- Gassy, fussy baby after feeds
- Slow weight gain despite frequent nursing
- Painful breastfeeding experience for mom
- Milk leaking from sides of baby’s mouth
- Short, heart-shaped, or restricted tongue movement
If your baby shows several of these symptoms, it’s worth getting a professional evaluation from a pediatric team experienced in tongue and lip tie diagnosis.
Why Early Treatment Matters
Early identification and treatment of tongue and lip ties can make a world of difference for your baby—and your entire feeding journey.
At Thrive Tongue Tie Clinic, we use a safe, gentle, and precise method for treatment: CO2 laser release. This approach is minimally invasive, often bloodless, and allows for quick healing with very little discomfort.
When done early, laser tongue tie release can:
- Improve latch almost immediately
- Boost milk transfer and feeding efficiency
- Relieve nipple pain for mothers
- Help baby gain weight faster and more consistently
- Reduce reflux and gas
- Enhance bonding between parent and child
- Minimize speech and dental issues later in life
What Happens During the Laser Procedure?
The idea of any procedure on your newborn can be overwhelming, but the truth is that CO2 laser treatment is one of the safest and gentlest options available.
Here’s what to expect:
- A Thorough Evaluation Our pediatric providers will perform a full assessment of your baby’s feeding, weight history, and oral anatomy.
- The Procedure Using our advanced CO2 laser, the tight tissue is quickly and precisely released with minimal bleeding and no stitches required. The procedure is often completed in just a few minutes.
- Post-Treatment Support After the procedure, we guide parents on gentle oral stretches and offer ongoing follow-up to ensure optimal healing and prevent reattachment.
- Pediatric-Focused Care We take a whole-child approach, supporting not just the physical outcome but also the emotional well-being of both baby and parent throughout the process.
Will My Baby Catch Up on Weight?
In most cases, yes. Once feeding efficiency improves, babies often begin to gain weight more rapidly. Parents frequently report seeing a noticeable difference within days or weeks of treatment. The earlier the intervention, the faster the recovery and progress.
When Should You See a Provider?
If you have concerns about your baby’s feeding, latch, or weight gain, don’t wait. Early diagnosis leads to early solutions. Whether you’re exclusively breastfeeding, bottle feeding, or doing both—support is available.

FAQs
1. How does a tongue-tied baby struggle with weight gain?
A tongue tied baby may have trouble latching properly, leading to poor milk transfer, longer feeds, and frequent hunger. This inefficiency often results in slower or inconsistent weight gain during early development.
2. What is laser tongue tie release and how does it help?
Laser tongue tie release is a gentle, minimally invasive procedure that uses a CO2 laser to precisely free the restricted tissue. It improves feeding by allowing better tongue movement, which helps babies latch effectively and gain weight more consistently.
3. Can both lip and tongue tie affect breastfeeding?
Yes, both lip and tongue tie can make breastfeeding painful or frustrating for the baby and mother. These conditions often prevent a secure latch, causing milk leakage, gas, and fussiness. Releasing the ties can significantly improve feeding.
4. Is laser tongue tie release safe for newborns?
Yes, laser tongue tie release is considered very safe for infants. The CO2 laser minimizes bleeding, swelling, and discomfort, making the procedure quicker and more comfortable than traditional methods.
5. When should parents seek treatment for a tongue tied baby?
Parents should seek evaluation if their tongue tied baby is showing signs of poor latch, frequent nursing, slow weight gain, or excessive fussiness after feeding. Early treatment of lip and tongue tie helps ensure proper growth and development.
