It is somewhat unexpected that fingernails become a source of significant parental anxiety in the first days and weeks of a baby's life. They are small, the baby moves, and there is a constant fear of nipping the skin. Yet newborn nails grow surprisingly fast – they can need attention as soon as the first or second week – and a baby who scratches their own face is another source of concern. This guide covers everything parents need to know about managing newborn nails.

Why Newborn Nails Need Attention Early
Newborns are born with nails that have been growing for months in the womb. By the time of birth, they can already be long enough to scratch, and because they are thin and sharp rather than hard, they can catch and cut skin easily. The baby's own face is the most common target; newborns move their hands toward their face frequently as a reflexive behaviour.
The nails of a full-term newborn may need trimming within the first week or two. Premature babies may have softer, less developed nails that need less immediate attention, though they should still be monitored.
Methods
Nail file. A fine emery board or soft nail file designed for infants is the gentlest and safest method for very young newborns. Filing does not risk cutting the skin and can be done during light sleep. The limitation is that it is slower than cutting and may not keep up with fast-growing nails.
Baby nail scissors. Small scissors with rounded tips, specifically designed for infant nail care, are safe when used correctly. The key technique: press the fingertip pad gently away from the nail as you cut, to create a gap between the nail and the skin. Cut in small increments across the nail rather than one large cut. Follow the natural curve of the nail.
Baby nail clippers. Some parents prefer small nail clippers. The approach is the same – press the fingertip pad back and cut carefully. Clippers give less visual control than scissors for some parents.
Biting. Some parents bite or peel their baby's nails. While this is traditional and widely practised, it can transfer oral bacteria to broken skin, and control is more limited than with scissors or a file. It is not recommended by healthcare providers.
When to Trim
The baby being still makes the task considerably easier. The best windows are:
During sleep. Light or active sleep (when the baby is moving slightly and not in deep sleep) is often ideal – the hands are still enough to work with but the baby is deeply enough asleep not to react.
After bathing. A bath softens the nails, making them slightly easier to cut with less risk of splitting.
During a feed. Some parents trim nails during a breastfeed, when the baby is calm and distracted.
Scratches and Mittens
If the baby does scratch their face, small surface scratches heal quickly and do not require treatment beyond keeping clean. Deeper or infected scratches should be assessed by a GP.
Scratch mittens (small fabric covers for the hands) are often provided in the first days and can prevent scratching in the short term. However, they should not be worn continuously for extended periods, because the hands and fingers are the primary way babies explore and learn tactile information. Research on early sensory development underlines the importance of hand and fingertip exposure to texture, temperature, and object properties in the first months. A balance – using mittens at sleep times if scratching is a concern, but removing them during awake periods – is a reasonable approach.
When Something Goes Wrong
Most parents accidentally nick the fingertip skin at some point; it is very common and usually results in a small bleed that stops quickly with gentle pressure. If the area shows signs of infection (redness, swelling, discharge, warmth) in the days after, a GP assessment is appropriate.
Paronychia (infection of the skin fold around the nail) is uncommon in newborns but can occur; it presents as a red, swollen, tender fold around a nail, sometimes with pus. It requires medical assessment.
Key Takeaways
Newborns' nails grow quickly and can scratch their own face and skin, sometimes causing minor wounds. The nails are soft but sharp. The most common parental concern is cutting the skin rather than the nail; this is usually avoided by using purpose-designed baby nail scissors or a fine nail file. Nail filing is the safest method for very young newborns. The best time to trim nails is when the baby is asleep or just after a bath, when the nails are softer. Mittens can prevent scratching in the short term but should not be used continuously as they reduce hand and tactile exploration.
