What Parents Should Know

According to AAP, CDC, NIH guidelines, pushing up on arms during tummy time is an important milestone that typically develops between 2-4 months. This skill builds upper body strength needed for rolling, sitting, and crawling. If your baby is not pushing up by 4 months, mention it to your pediatrician. Many babies just need more tummy time practice. At 0-2 months, at this age, your baby may only briefly lift their head during tummy time, and that is normal. Pushing up on arms comes later. Short periods of tummy time several times a day help build the strength needed for this milestone. Even a few minutes at a time counts. It is generally considered normal when your baby is under 3 months and is starting to lift their head during tummy time. However, you should contact your pediatrician promptly if your baby was pushing up and has lost this ability.

By Age

What to expect by age

0-2 months

At this age, your baby may only briefly lift their head during tummy time, and that is normal. Pushing up on arms comes later. Short periods of tummy time several times a day help build the strength needed for this milestone. Even a few minutes at a time counts.

2-4 months

Most babies begin pushing up on their forearms (mini push-up position) around 2-3 months and progress to pushing up on straight arms by 4 months. If your baby is not pushing up on forearms by 3 months, increase tummy time and try placing a rolled towel under their chest for support. If there is no progress by 4 months, mention it to your doctor.

4-6 months

By 4-6 months, your baby should be able to push up on extended arms and look around during tummy time. If your baby still cannot push up on their forearms, this warrants evaluation. Low muscle tone, upper body weakness, or other factors may be contributing and can often be addressed with physical therapy.

6-9 months

If your baby is not bearing weight through their arms by this age, a physical therapy evaluation is important. Weight bearing through arms is essential for crawling and protective reflexes when falling. Early intervention can significantly help build this strength.

What to Tell Your Pediatrician

  • Describe when you first noticed won't push up on arms during tummy time 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 is over 4 months and cannot push up on forearms during tummy time.
  • Mention if your baby's arms seem floppy or weak.
  • 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.

Baby Not Pushing Up on Tummy

Pushing up during tummy time develops gradually over the first 6 months. Babies begin by lifting their head briefly around 1 to 2 months, progress to propping on forearms by 3 to 4 months, and push up on extended arms by 5 to 6 months. Short, frequent tummy time sessions are the best way to build this strength, even if your baby is not a fan of being on their tummy.

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 Has Delayed Head Control

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.

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.

Baby-Proofing a Small Apartment

Baby-proofing a small apartment is absolutely possible and focuses on the same key safety principles as any home: securing furniture to walls, covering outlets, locking cabinets with hazardous materials, and ensuring safe sleep spaces. Small spaces actually have an advantage - there is less area to monitor. Focus on eliminating the most dangerous hazards first: falls, poisoning, choking, and burns.

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.
