My Baby Has Delayed Head Control
The short answer
Head control develops gradually over the first 4 months. Most babies can hold their head steady when held upright by 4 months. If your baby has significant head lag or cannot hold their head steady by 4 months, mention it to your pediatrician. It may indicate low muscle tone that can be addressed with exercises or therapy.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
Newborns have very limited head control and need their heads supported at all times. Your baby may briefly lift their head during tummy time. This is completely normal. Head control develops gradually over the coming weeks.
Your baby should be gaining head control, lifting their head 45 degrees or more during tummy time and holding it more steadily when held upright. Some wobbliness is still normal. If your baby shows no improvement in head control from the newborn period, mention it to your pediatrician.
Most babies have good head control by 3-4 months, holding their head steady when sitting supported and lifting it well during tummy time. If your baby still has significant head lag when pulled to sitting or cannot hold their head steady when held upright, discuss this with your doctor.
Head control should be well established by this age. If your baby still has poor head control, evaluation is important. Conditions like hypotonia (low muscle tone) are common and treatable. Physical therapy can make a significant difference in building neck and core strength.
What Should You Do?
When to take action
- Your baby is under 3 months and head control is gradually improving.
- Your baby has some wobbliness but can hold their head for short periods.
- Your baby was premature and is on track for their adjusted age.
- Your baby lifts head well during tummy time but is wobbly when held upright.
- Your baby is over 3 months and cannot hold their head steady when held upright.
- Your baby has significant head lag when pulled gently from lying to sitting.
- Your baby's head control is not improving week to week.
- Your baby had head control and has lost it.
- Your baby seems increasingly floppy or weak throughout their body.

Related Physical Concerns
My Baby Has Head Lag
Head lag - when your baby's head falls backward as you gently pull them from lying down to sitting - is normal in young babies. Most babies develop enough neck strength to keep their head in line with their body during this movement by about 4 months. If significant head lag persists past 4 months, it's worth discussing with your pediatrician.
Low Muscle Tone (Hypotonia)
Low muscle tone means your baby's muscles feel less firm or their body feels "floppy" when you hold them. While it can sometimes indicate an underlying condition, many babies with mildly low tone do very well with support and strengthening activities.
My Baby Seems Floppy (Hypotonia)
A "floppy" baby is one whose muscles feel unusually relaxed and who may slip through your hands when you lift them under the arms. Many cases of mild floppiness improve on their own as your baby grows stronger, but it is important to have your pediatrician evaluate your baby to rule out any underlying conditions.
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.
