Cord Stump Still Attached (Delayed Separation)
The short answer
The umbilical cord stump typically falls off within 1-3 weeks, but it can take up to 4 weeks or occasionally longer. Do not pull it off, as it will separate naturally. Keep it clean and dry. If the stump has not fallen off by 4 weeks, mention it to your pediatrician. Very delayed separation (beyond 6-8 weeks) can rarely indicate an immune deficiency.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
The cord stump dries, shrivels, and separates naturally. Most fall off between 7-21 days, but the range is wide. Factors that affect timing include: how the cord was clamped, stump thickness, exposure to air, and individual variation. Do not pull, twist, or force the stump off, even if it seems to be hanging by a thread. Let it fall off naturally. Keep the area clean and dry, fold diapers below it, and allow air exposure. Bathing with sponge baths (not submersion) is recommended until it falls off.
If the cord stump was delayed but eventually fell off, monitor the belly button for normal healing. An umbilical granuloma (small pink tissue growth) may develop at the site, which your pediatrician can treat. If the stump has not separated by 6-8 weeks, your pediatrician may investigate for rare conditions such as leukocyte adhesion deficiency (an immune disorder).
The belly button should be fully healed. Any persistent drainage, tissue, or concerns at the belly button should be evaluated.
No cord-related concerns. Normal belly button hygiene during baths.
What Should You Do?
When to take action
- Cord stump separating within 1-4 weeks
- Stump appears dry, dark, and shriveled
- Small amount of blood or clear drainage when the stump separates
- No redness or swelling at the base
- Cord stump has not fallen off by 3-4 weeks
- The stump looks wet, oozy, or is not drying well
- You are tempted to pull it off and want guidance
- Cord stump with redness, swelling, foul smell, or pus indicating infection
- Cord stump has not separated by 6-8 weeks, which may warrant immune evaluation
- Heavy bleeding from the cord site

Related Medical Concerns
Smelly Umbilical Cord Stump
A mild odor from the umbilical cord stump as it dries and separates is normal. However, a strong, foul, or unpleasant smell can be a sign of infection (omphalitis) and should be evaluated by your pediatrician. Other signs of infection include redness, swelling, warmth, or discharge from the base of the cord stump.
Oozing After Cord Falls Off
A small amount of clear or slightly bloody fluid from the belly button after the cord stump falls off is common and usually harmless. This minor oozing typically resolves within a few days with gentle cleaning and keeping the area dry. Persistent oozing may indicate an umbilical granuloma, which your pediatrician can easily treat.
Umbilical Granuloma (Tissue Growth After Cord Falls Off)
An umbilical granuloma is a small, moist, pink or red tissue growth that can form at the belly button after the umbilical cord stump falls off. It is not painful and is very common. It usually needs to be treated with silver nitrate application by your pediatrician to help it dry up and heal, which is a quick and painless in-office procedure.
My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
