How to Support Muscle Strength, Balance, and Coordination

Medically reviewed by pediatrician and perinatal psychologist Polina Kizino

Strength, balance, and coordination grow through everyday movement and play. Let your baby crawl, stand, and explore at their own pace. No workouts needed — just comfy clothes, a safe space, and plenty of freedom.

Quick takeaways

  • Around 9–10 months, babies start developing control over their bodies — they learn to balance, stand, crawl, and sit.
  • Healthy development requires free movement, floor time, comfortable clothes, varied surfaces, and a safe environment.
  • Simple games and daily playtime support strength and balance better than any equipment or complex techniques.
  • Don’t rush things — skills develop differently for each baby. Follow their signals and natural pace.
  • The parent's role is not to teach, but to support: remove obstacles, offer encouragement, and observe.

What’s happening in your baby’s body

At this age, your baby may already:

  • crawl or try to
  • pull up to stand
  • cruise along furniture
  • sit steadily

These actions require coordination of many muscle groups — especially the core, back, hips, and feet.

Their vestibular system (balance) and proprioception (awareness of body position) are also developing.

👣

In simple terms: your baby’s brain is learning how to control the body — understanding where it is and how to stay steady during movement.

How to support strength and coordination

More floor time

The best thing you can do is offer your baby a safe, clean, and engaging space on the floor. Let them crawl, stand, sit, and explore toys.

🕧

Ideally, aim for at least 1–2 hours of active floor time per day (outside of strollers, swings, and seats) — not all at once, but in total.

Varied surfaces

Use textured mats, soft mattresses, and safe pillows. These help stimulate the feet, encourage balance, and activate different muscles.

Barefoot at home

Walking barefoot helps develop the foot arch and supports healthy muscle activity.

Interactive games

  • Roll a ball back and forth
  • Hidetoys and let your baby crawl to find them
  • Use pillows as tunnels or little ramps
  • These simple activities boost muscle development, coordination, focus, and curiosity

Support without pushing

If your baby isn’t ready for a movement, don’t force it. For example, don’t hold their hands to “teach” walking. All activities should follow your baby’s pace.

When to consult a pediatrician

If by 10 months your baby:

  • can’t sit up independently
  • doesn’t roll or crawl at all
  • doesn’t bear weight on their legs when held under the arms

Sometimes it’s just a variation of normal — but it’s worth gently checking in with a specialist for support.

Frequently Asked Questions About Muscle Strength, Balance, and Coordination

What can a baby usually do at 9–10 months?

Usually at 9–10 months, babies are actively improving body control and coordination. Many can sit steadily, crawl or try to crawl, pull up to stand, and move along furniture while holding on. These skills show developing balance and body awareness. Parents can help by offering a safe floor space every day for free movement, play, and exploration.

Why is free movement important?

Free movement is important because it naturally builds strength, balance, and coordination. When a baby crawls, sits, pulls to stand, and explores, the core, back, hip, and foot muscles all work together with the balance systems. Aim for 1–2 total hours of active floor time daily, outside strollers, swings, and seats, in a safe environment.

How can I support coordination and balance?

You can support coordination through daily active play and safe exploration. Let your baby crawl, reach for toys, pull up near stable furniture, and move across different surfaces such as textured mats, soft mattresses, and safe pillows. Rolling a ball, hiding toys to encourage crawling, and using pillows as tunnels or small ramps help build muscles, focus, curiosity, and confidence.

Should my baby be barefoot at home?

Yes, being barefoot at home can help if the floor is safe and comfortable. Bare feet support healthy foot muscle activity, help the foot arch develop, and let the baby feel different surfaces more clearly. That sensory feedback supports balance and coordination. Combine barefoot play with 1–2 hours of active floor time, comfortable clothes, and safe varied surfaces.

When should I talk to a pediatrician?

Talk to a pediatrician if by 10 months your baby shows a noticeable delay in motor development. Important signs include not sitting independently, not rolling, not crawling at all, or not bearing weight on the legs when held under the arms. Sometimes this is normal variation, but a specialist can assess overall development and suggest support if needed.
