When the tongue is restricted - lip blisters or callus's often arise. Here's an image
A lip blister (sometimes called a “sucking blister”) is a small bubble, thickened patch, or callus that can form on the upper or lower lip.
Many parents are told this means baby has a “strong suck.”Sometimes that’s true.
But often, as we discuss - it’s actually a sign that baby is working harder than they need to in order to maintain suction.
So rather than being a sign of “strength,” it’s often a sign of compensation.
Not every blister means there is tongue restriction — but when paired with other feeding challenges, it can give helpful clues about latch mechanics.
What parents may notice:
- A small blister, bubble, or white callused area on the upper lip
- A thickened strip across the centre of the lip
- Lips curling inward during feeds instead of flanging outward
- Clicking sounds while feeding
- Frequent loss of suction
- Milk leaking from the sides of the mouth
- Baby tiring quickly or feeding for long periods
What it can look like:
- A clear fluid-filled bubble that comes and goes
- A dry, peeling or thickened patch
- A lip that folds under rather than staying relaxed and outward
Why this can matter:
Feeding should be rhythmic and efficient.
If baby cannot maintain a stable seal with the lips and tongue, they may compensate by:
- Increasing pressure through the lips
- Using more jaw effort
- Clamping or sliding on the nipple
- Repeatedly breaking and re-establishing suction
Over time, this extra friction can create a blister or callus.
