Cutting Newborn Nails Safely
The short answer
Newborn nails are soft but surprisingly sharp and grow quickly. You can start trimming them within the first few weeks. Use baby nail clippers, baby scissors with rounded tips, or a gentle nail file. Many parents find it easiest to trim nails while the baby is sleeping. Accidentally nicking the skin is common and heals quickly.
Thousands of parents search for this exact thing. You are not alone.
By Age
What to expect by age
Newborn fingernails are thin and soft but can be sharp enough to scratch your baby's face. You may need to trim them as early as the first week. Options include: filing with a soft emery board (safest, easiest for nervous parents), using baby nail clippers or rounded-tip scissors, or gently peeling off soft tips with your fingers. Many parents find it easiest to trim nails while the baby is asleep or feeding. If you accidentally nick the skin (very common), apply gentle pressure with a clean cloth; the bleeding stops quickly. Do not use adult-sized clippers.
Nails continue to grow quickly and may need trimming weekly. You will become more confident with practice. Toenails grow more slowly and may only need trimming monthly.
As baby becomes more active with their hands, keeping nails trimmed prevents scratching. Filing after clipping helps smooth any sharp edges.
Baby may resist nail trimming as they become more mobile. Continue trimming during sleep or use distraction techniques during awake trims.
What Should You Do?
When to take action
- Nails that need trimming every few days to weekly
- Baby scratching their own face (common and preventable with nail care)
- Occasional minor nick during trimming that stops bleeding quickly
- Nails seem unusually thick, discolored, or misshapen
- You accidentally cut deeper and bleeding does not stop within 10 minutes
- You notice signs of nail infection (redness, swelling around the nail)
- Significant bleeding from a nail trim injury that does not stop with pressure
- Signs of infection: red, swollen, pus-draining area around a nail

Related Physical Concerns
Baby Scratching Own Face
Newborns commonly scratch their own faces because their movements are uncoordinated and their nails are sharp. This is normal and not a sign of distress. Regular nail trimming is the best prevention. Mittens can be used temporarily but should not be used long-term as babies need to explore with their hands.
My Baby Seems to Use One Side More Than the Other
Babies should use both sides of their body fairly equally during the first 18 months of life. While slight preferences can be normal, a consistent pattern of favoring one side - using one arm much more than the other, crawling with one leg dragging, or turning the head predominantly one way - should always be discussed with your pediatrician. Early identification of asymmetry leads to the best outcomes.
My Baby Only Army Crawls
Army crawling (also called commando crawling) is a completely valid and normal way for babies to move. Many babies army crawl for weeks or even months before transitioning to hands-and-knees crawling, and some skip hands-and-knees crawling entirely. What matters is that your baby is independently mobile and exploring their environment.
One Side of My Baby's Body Moves Differently
Babies should generally use both sides of their body equally. If one side consistently moves differently, is weaker, stiffer, or less coordinated, this warrants evaluation. Asymmetric movement can indicate hemiplegia (cerebral palsy affecting one side), brachial plexus injury, or other neurological conditions that benefit from early therapy.
My Baby Crawls Unevenly
While some variation in crawling patterns is normal, consistently favoring one side or dragging one limb while crawling warrants attention. Babies should use both arms and both legs relatively equally when crawling. Persistent asymmetry could indicate muscle tone differences, hip issues, or neurological concerns that benefit from early evaluation.
My Baby Still Has the Fencing Reflex (Persistent ATNR)
The asymmetric tonic neck reflex (ATNR, also called the fencing reflex) causes your baby to extend the arm on the side they are looking toward. It should integrate between 4-6 months. If the ATNR persists strongly beyond 6 months, it can interfere with bringing hands to midline, bilateral hand use, and rolling. Evaluation is recommended.
