If your baby has been diagnosed with or you suspect has a brain bleed (intraventricular hemorrhage), here is what the evidence says.
The short answer
Intraventricular hemorrhage (IVH) is bleeding into or around the brain's ventricles, most common in premature babies born before 32 weeks. It is graded 1 through 4: grades 1-2 are mild and usually resolve without lasting effects, while grades 3-4 are more serious and may lead to hydrocephalus, developmental delays, or cerebral palsy. Hearing that your baby has a brain bleed is terrifying, but it is important to know that even with higher grades, outcomes vary and many children do well with appropriate follow-up and early intervention.
Key takeaways
- Intraventricular hemorrhage (IVH) is bleeding into or around the brain's ventricles, most common in premature babies born before 32 weeks. It is graded 1 through 4: grades 1-2 are mild and usually resolve without lasting effects, while grades 3-4 are more serious and may lead to hydrocephalus, developmental delays, or cerebral palsy.

- Usually normal when: Your baby has grade 1-2 IVH and the NICU team is following with serial ultrasounds — this is very common in preemies
- Call your doctor if: Your baby has seizures — call 911 or go to the emergency room immediately
- Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to NIH, March of Dimes, Stanford Medicine guidelines, intraventricular hemorrhage (IVH) is bleeding into or around the brain's ventricles, most common in premature babies born before 32 weeks. It is graded 1 through 4: grades 1-2 are mild and usually resolve without lasting effects, while grades 3-4 are more serious and may lead to hydrocephalus, developmental delays, or cerebral palsy. Hearing that your baby has a brain bleed is terrifying, but it is important to know that even with higher grades, outcomes vary and many children do well with appropriate follow-up and early intervention. At Diagnosis in NICU (first 3 days of life), most IVH occurs within the first 72 hours of life. It is usually detected on routine head ultrasounds performed on premature babies. Grade 1-2 bleeds are very common in extremely premature infants (occurring in up to 25-30%) and typically resolve on their own. Grade 3-4 bleeds are less common but more concerning. Your NICU team will monitor with serial ultrasounds to track whether the bleed is stable, resolving, or causing complications like hydrocephalus. It is generally considered normal when your baby has grade 1-2 IVH and the NICU team is following with serial ultrasounds — this is very common in preemies. However, you should contact your pediatrician promptly if your baby has seizures — call 911 or go to the emergency room immediately.
Normal vs. Concerning
When to Seek Immediate Care
- Your baby has seizures — call 911 or go to the emergency room immediately
- Your baby's fontanelle is bulging, they are vomiting, or they are unusually difficult to wake — these may be signs of increased pressure and require emergency evaluation
- Your baby has a sudden change in consciousness or responsiveness
By Age
What to expect by age
Diagnosis in NICU (first 3 days of life)
Most IVH occurs within the first 72 hours of life. It is usually detected on routine head ultrasounds performed on premature babies. Grade 1-2 bleeds are very common in extremely premature infants (occurring in up to 25-30%) and typically resolve on their own. Grade 3-4 bleeds are less common but more concerning. Your NICU team will monitor with serial ultrasounds to track whether the bleed is stable, resolving, or causing complications like hydrocephalus.
0-3 months corrected age
After discharge, babies with grade 1-2 IVH are typically followed with routine developmental monitoring. Those with grade 3-4 IVH need closer follow-up including repeat imaging and neurological assessments. If hydrocephalus develops (fluid buildup in the brain), it may require a shunt or reservoir — your neurosurgeon will explain the options. Signs of hydrocephalus include a rapidly growing head circumference, bulging fontanelle, and increased irritability.
3-12 months corrected age
Developmental outcomes become clearer during this period. Many babies with grade 1-2 IVH develop normally. Those with grade 3-4 IVH may show motor delays, particularly in the legs. Physical therapy, occupational therapy, and speech therapy (if needed) should begin early. Your developmental pediatrician will help coordinate care and set realistic, hopeful goals.
12 months+ corrected age
Long-term outcomes depend heavily on the grade and whether complications like hydrocephalus occurred. Many children with low-grade IVH have no lasting effects. Those with higher-grade bleeds may have motor or learning challenges that benefit from ongoing therapy and educational support. Continued developmental monitoring through school age is recommended.
What to Tell Your Pediatrician
- Describe when you first noticed has a brain bleed (intraventricular hemorrhage) and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your baby's head circumference is growing faster than expected on the growth chart.
- Mention if your baby seems excessively irritable, is feeding poorly, or has changes in alertness.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your baby has grade 1-2 IVH and the NICU team is following with serial ultrasounds — this is very common in preemies
- Follow-up imaging shows the bleed is stable or resolving
- Your baby is meeting developmental milestones with or without early intervention support
- Your baby's head circumference is growing faster than expected on the growth chart
- Your baby seems excessively irritable, is feeding poorly, or has changes in alertness
- You are concerned about motor development — your baby seems stiff, floppy, or prefers one side
- You have questions about the long-term implications of your baby's IVH grade
- Your baby has seizures — call 911 or go to the emergency room immediately
- Your baby's fontanelle is bulging, they are vomiting, or they are unusually difficult to wake — these may be signs of increased pressure and require emergency evaluation
- Your baby has a sudden change in consciousness or responsiveness
What You Can Do at Home
- Keep track of when you notice has a brain bleed (intraventricular hemorrhage) — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby has grade 1-2 IVH and the NICU team is following with serial ultrasounds — this is very common in preemies — this is generally within the range of normal.
- At Diagnosis in NICU (first 3 days of life), focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if your baby has seizures — call 911 or go to the emergency room immediately.
Related Conditions
My Baby Was Diagnosed with PVL (Periventricular Leukomalacia)
Periventricular leukomalacia (PVL) is a type of white matter brain injury that occurs most commonly in premature babies. It involves damage to the tissue around the brain's ventricles, which carries nerve fibers controlling motor movements. PVL is one of the most common brain injuries in preterm infants and can range from mild (small focal areas) to more extensive involvement. While PVL is associated with an increased risk of cerebral palsy and developmental delays, outcomes vary widely depending on severity, and early intervention can make a significant difference.
Should I Use Adjusted Age for My Preemie's Milestones?
Yes — for premature babies, developmental milestones should be assessed using adjusted (corrected) age, not chronological age, until at least 2 years of age. Adjusted age is calculated by subtracting the number of weeks your baby was born early from their actual age. For example, a 6-month-old born 2 months early would have an adjusted age of 4 months, and should be assessed against 4-month milestones. Most pediatricians use adjusted age for developmental assessment through age 2-3, and for growth charts through age 2.
NICU Parent Trauma and Stress
Having a baby in the NICU is one of the most stressful experiences a parent can face. Research shows that up to 70% of NICU parents experience clinically significant anxiety or depression, and a substantial number develop PTSD symptoms. The helplessness, fear, separation from your baby, and disruption of expected parenthood are legitimately traumatic. Your pain is real and you deserve support.

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.
