Your baby's physical development is unique, and concerns about only cruises in one direction, here is what you need to know.

The short answer

When babies first start cruising, it is common to go in one direction more easily than the other. This is because side-stepping requires leading with one foot, and babies naturally favor one side initially. Most babies learn to cruise both directions within a few weeks. Persistent one-direction cruising lasting more than a month should be mentioned to your pediatrician.

Key takeaways

  • When babies first start cruising, it is common to go in one direction more easily than the other. This is because side-stepping requires leading with one foot, and babies naturally favor one side initially. Most babies learn to cruise both directions within a few weeks. Persistent one-direction cruising lasting more than a month should be mentioned to your pediatrician.
  • Usually normal when: Your baby just started cruising and prefers one direction.
  • Call your doctor if: Your baby has sudden weakness on one side of their body.
  • Varies by age — see the age-by-age breakdown below
Supervised tummy time is recommended daily from the time the baby comes home from the hospital to help prevent flat head syndrome and to strengthen neck and shoulder muscles.

What Parents Should Know

According to AAP, CDC, NIH guidelines, when babies first start cruising, it is common to go in one direction more easily than the other. This is because side-stepping requires leading with one foot, and babies naturally favor one side initially. Most babies learn to cruise both directions within a few weeks. Persistent one-direction cruising lasting more than a month should be mentioned to your pediatrician. At 9-11 months, when cruising first begins, preferring one direction is very common. Your baby is figuring out the side-stepping motion and naturally leads with one foot. Give them time to develop comfort in both directions. You can encourage the other direction by placing toys on the non-preferred side. It is generally considered normal when your baby just started cruising and prefers one direction. However, you should contact your pediatrician promptly if your baby has sudden weakness on one side of their body.

By Age

What to expect by age

9-11 months

When cruising first begins, preferring one direction is very common. Your baby is figuring out the side-stepping motion and naturally leads with one foot. Give them time to develop comfort in both directions. You can encourage the other direction by placing toys on the non-preferred side.

11-13 months

Most babies cruise in both directions by now, though they may still have a preferred side. If your baby exclusively cruises one way and seems unable to go the other direction, watch for other signs of asymmetry like favoring one hand or one leg seeming stiffer.

13-15 months

If your baby still cannot cruise both directions, mention it to your pediatrician. They may want to check for asymmetry in muscle tone or strength. Some babies transition to walking even if they only cruised one direction, which may resolve the concern.

15-18 months

If your child has started walking, observe whether they walk symmetrically. If walking also seems asymmetric, evaluation is recommended. If walking looks normal, the one-direction cruising was likely just a preference.

What to Tell Your Pediatrician

  • Describe when you first noticed only cruises in one direction 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 exclusively cruises in one direction for more than 4-6 weeks.
  • Mention if your baby seems unable to step to one side.
  • 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

Probably normal when...
  • Your baby just started cruising and prefers one direction.
  • Your baby can cruise both ways but prefers one.

What You Can Do at Home

  • Keep track of when you notice only cruises in one direction — noting the time of day, duration, and any triggers can help your pediatrician.
  • Remember that your baby just started cruising and prefers one direction — this is generally within the range of normal.
  • At 9-11 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
  • Provide plenty of supervised floor time and tummy time to support your baby's physical development.
  • While monitoring at home, seek immediate care if your baby has sudden weakness on one side of their body.

My Baby Isn't Cruising Along Furniture

Cruising - walking sideways while holding onto furniture - typically begins between 8 and 12 months. Some babies cruise for weeks before walking independently, while others barely cruise at all and go straight from pulling to stand to walking. The timeline varies enormously, and cruising itself is not a required milestone.

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 Cruises but Won't Let Go and Walk

The time between cruising and independent walking varies enormously, from a few days to several months. Most babies cruise for 1-3 months before walking independently. Cruising shows your baby has the strength and balance foundations for walking - they just need to build the confidence to let go. This transition period is completely normal.

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 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.
