Flat Head at 7 Months: What Parents Need to Know
If you’ve noticed your baby’s head looks a little flat on one side or the back, you’re not alone. Many parents spot this around the 4- to 7-month mark and wonder, How worried should we be? Let’s break down what’s normal, when to take action, and how to support healthy head shape development in infants.
What Causes a Flat Head in Babies?
During the first year of life, a baby’s skull is soft and malleable to accommodate rapid brain growth. This flexibility, while essential, also makes their head susceptible to flattening when pressure is applied repeatedly to one spot. The most common causes include:
– Sleep position: Babies spend a lot of time on their backs (as recommended for safe sleep), which can lead to flattening at the back of the head.
– Limited movement: If a baby prefers turning their head to one side due to neck tightness (torticollis) or habit, it increases pressure on that area.
– Multiple births or prematurity: Babies in cramped prenatal conditions or those born early often have softer skulls, making flattening more likely.
At 7 months, some flattening is fairly common. The good news? Most cases improve with simple interventions and don’t affect brain development.
When Should You Be Concerned?
Not all flat spots are the same. Here’s how to assess the situation:
1. Mild flattening: If the flat area is slight and your baby moves their head freely in both directions, this often resolves on its own as they start sitting up, crawling, and spending less time lying down.
2. Moderate to severe flattening: A noticeably asymmetrical head shape, especially if paired with facial asymmetry (like one ear appearing more forward than the other), may need professional evaluation.
3. Unusual head shapes: A rigid, unmoving flat spot or a ridge along the skull could indicate a rare condition called craniosynostosis, where skull bones fuse prematurely. This requires medical attention.
Red flags to watch for:
– Difficulty turning the head in both directions.
– Delayed motor skills (e.g., not rolling over by 7 months).
– A bulging or sunken soft spot (fontanelle).
If you observe any of these, consult your pediatrician promptly.
What Can Parents Do at Home?
For mild to moderate flattening, these strategies often help:
1. Increase Tummy Time
Supervised tummy time strengthens neck and shoulder muscles, reducing pressure on the head. Aim for at least 30-60 minutes spread throughout the day. If your baby resists, try lying face-to-face with them or placing toys within reach.
2. Alternate Head Positions
During naps and feedings, gently turn your baby’s head to the non-preferred side. Use rolled-up blankets or specially designed pillows (approved for safe sleep) to encourage this.
3. Hold Your Baby More
Carrying your baby in your arms, a sling, or a carrier reduces time spent lying flat. Bonus: It’s great for bonding!
4. Change the Crib Setup
Babies naturally look toward light, voices, or interesting objects. Rotate the crib’s position weekly or switch which end you place them in to encourage head-turning variety.
5. Address Neck Tightness
If your baby favors one side due to tight neck muscles, ask your pediatrician about gentle stretching exercises or physical therapy.
When to Seek Professional Help
If home strategies don’t improve the flat spot by 9-12 months, or if the asymmetry seems severe, a pediatrician might recommend:
– Helmet therapy (cranial orthosis): Custom-made helmets gently reshape the skull over several months. These are most effective between 4 and 12 months when the skull is still soft.
– Physical therapy: For babies with torticollis or motor delays, targeted exercises can improve mobility.
While helmets can look intimidating, studies show they’re safe and effective when used appropriately. However, they’re not always necessary—many babies improve without them.
Preventing Flat Head Syndrome
Prevention starts early, but even at 7 months, these habits help:
– Vary activities: Alternate between back, tummy, and side-lying positions during play.
– Limit time in containers: Minimize use of car seats, swings, and bouncers when not essential.
– Encourage exploration: Once your baby can sit independently, they’ll naturally spend less time on their back.
The Bottom Line
At 7 months, a flat head is usually a cosmetic concern rather than a medical emergency. While it’s natural to worry, most babies’ head shapes improve with time and active repositioning. Trust your instincts—if something feels off, discuss it with your pediatrician. Remember, every baby develops at their own pace, and early intervention (when needed) makes a big difference.
Keep an eye on progress, celebrate small milestones, and rest assured that you’re doing your best to support your little one’s growth. Parenthood is full of worries, but this is one that often smooths out—literally—with patience and care.
