Baby toenails often split because they are exceptionally thin.
The Thin Nail Factor
Newborns, and even children up to age 2, commonly experience nail splitting, particularly on the thumbnails and big toes. This is primarily attributed to the delicate nature of their nails; because baby nails are so thin, they are more susceptible to damage and splitting. About 1 in 3 newborns experience this.
Contributing Factors
While thinness is the primary reason, other factors can exacerbate the problem:
- Thumb Sucking: This habit can introduce moisture and pressure, weakening the nail structure and leading to splits.
- Trauma: Even minor bumps and scrapes can easily damage thin baby nails.
- Dryness: Dry environments can cause nails to become brittle and prone to splitting.
What to Do About Split Baby Toenails
While concerning, split baby toenails are usually not a serious medical issue. Here are a few things you can do:
- Keep Nails Trimmed: Regularly trim the nails to prevent snags and further splitting. Use baby nail clippers or scissors with rounded edges.
- Moisturize: Applying a baby-safe moisturizer to the nails and surrounding skin can help prevent dryness.
- Avoid Harsh Chemicals: Limit exposure to harsh soaps or chemicals that can dry out the nails.
- Consult a Pediatrician: If the splitting is severe, accompanied by redness, swelling, or discharge, consult a pediatrician to rule out any underlying conditions.
In most cases, split baby toenails resolve on their own as the nails thicken with age.
