Mottled or Marbled Skin in Newborns (Cutis Marmorata)
The short answer
Mottled or marbled-looking skin (cutis marmorata) is very common in newborns and young babies. It appears as a lacy, bluish-red pattern on the skin and typically occurs when your baby is cold or during temperature changes. It is almost always a normal, harmless finding that resolves as your baby grows.

By Age
What to expect by age
Mottling is very common in newborns because their blood vessels and temperature regulation are still immature. You may notice a lace-like, marbled pattern on the skin, especially on the trunk and extremities, when your baby is undressed, cold, or during a bath. The pattern typically fades quickly when your baby is warmed. This is a normal physiological response and does not indicate illness in an otherwise well-appearing newborn.
Mottling may continue but usually becomes less pronounced as your baby's circulatory system matures. You may still see it during baths, diaper changes, or when moving from a warm to a cooler environment. If the mottling resolves with warming and your baby is feeding and behaving normally, it is not a cause for concern.
By this age, mottling should be much less frequent. Occasional mottling during temperature changes is still normal, but persistent or worsening mottling at this age should be mentioned to your pediatrician, especially if your baby also seems unwell.
Mottling should be rare at this age. Persistent cutis marmorata beyond 6 months may sometimes be associated with other conditions and should be discussed with your doctor. Brief episodes related to cold exposure remain normal.
What Should You Do?
When to take action
- Lacy, marbled skin pattern that appears when baby is cold or undressed and resolves with warming
- Mottling that comes and goes, especially during baths or temperature changes
- Baby is otherwise well, feeding normally, and has good energy
- The pattern fades quickly when baby is bundled or warmed
- Mottling seems to be getting more frequent or persistent over time
- The mottled pattern does not resolve when baby is warmed
- Mottling is present on one side of the body only or in a fixed pattern
- Persistent mottling along with lethargy, poor feeding, fever, or other signs of illness, which could indicate infection or circulatory problems
- Widespread mottling that does not improve with warming along with rapid breathing, grunting, or color changes of the lips and tongue

Related Medical Concerns
Blue Hands and Feet in Newborns (Acrocyanosis)
Blue or purple hands and feet in a newborn (acrocyanosis) is very common and almost always normal in the first few days of life. It happens because your baby's circulation is still maturing and blood flow to the extremities is adjusting to life outside the womb.
My Baby Turns Blue (Cyanosis)
Blue or purple discoloration limited to a baby's hands and feet (acrocyanosis) is very common in newborns and usually harmless, caused by immature circulation. However, blue coloring of the lips, tongue, face, or trunk (central cyanosis) is always a medical emergency that requires immediate evaluation, as it may indicate a heart or lung problem.
Ideal Room Temperature for Baby
The ideal room temperature for a sleeping baby is between 68-72 degrees F (20-22 degrees C). A room that is too warm increases the risk of SIDS. Dress your baby in one layer more than you would wear comfortably, and check their chest or back of neck to assess temperature rather than hands or feet.
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.
