Have you ever noticed a little 💗 shape at the tip of your baby’s tongue when they cry?
That heart shape can be a strong sign of a tongue tie.
Here’s why it happens:
The tissue under the tongue (the frenulum) is anchored a little tighter or shorter than it should be. When baby lifts or cries and the tongue tries to move forward, that tight tissue creates tension, pulling the center of the tongue back and leaving the sides more free. The result? A little heart-shaped dip at the tip.
But here’s the important part:
We don’t diagnose tongue ties by looks alone. We diagnose by function.
If that heart shape is paired with feeding challenges, it’s worth a closer look.
Other signs that may show up alongside it:
• Difficulty latching or staying latched
• Clicking sounds while feeding
• Leaking milk from the sides of the mouth
• Gumming or chewing at the breast
• Prolonged feeds but still seeming hungry
• Falling asleep quickly at the breast from fatigue
• Slow weight gain
• Maternal ni**le pain, damage, blanching, or lipstick-shaped ni**les after feeds
• Recurrent clogged ducts or mastitis from ineffective milk removal
You might also notice baby has limited tongue lift, can’t stick their tongue past their gums, or the tongue seems to move in a choppy or piston-like motion instead of a smooth wave.
Not every heart-shaped tongue needs a procedure. Some babies compensate beautifully. Some need bodywork or feeding support. Some benefit from a release. It’s nuanced.
If you’re seeing the heart shape and feeding feels harder than it should, trust that instinct. A skilled IBCLC and a provider trained in oral function can assess the whole picture, not just the appearance.
Because feeding shouldn’t hurt.
And you deserve answers, not dismissal. đź’•
