Welcome to The Milestone

Here’s a safer, more modernized version that preserves your OT expertise while substantially reducing medical/diagnostic/developmental-treatment risk language:

“Wow, your baby has great muscle tone!”

Many parents have heard a comment like that before. It’s usually meant as a compliment — but it also raises a reasonable question:

What exactly is muscle tone?

Let’s break it down in a simple and practical way.

In general, muscle tone refers to the natural level of tension and readiness within our muscles that helps support posture, movement, and stability throughout everyday life. It’s part of what helps us hold our head upright, maintain posture while sitting, and respond to movement without consciously thinking about every adjustment our body makes.

And just like adults, babies can show a wide range of natural variation in how they move, position themselves, and respond to movement experiences.

Some babies may appear naturally more active or stiff during movement and positioning, while others may appear more relaxed and flexible. Most babies fall somewhere in between — and all babies continue developing movement skills and body awareness over time through everyday experiences and interaction.

One important thing to understand is that movement development is a process. Babies are continuously learning how to coordinate their body, respond to sensory input, and explore movement in more organized ways as they grow.

That’s why supervised movement opportunities and position changes during awake time can be so valuable during infancy.

For some babies, this may look like gradually becoming more comfortable with tummy-time and lifting their head against gravity. For others, it may involve encouraging opportunities for reaching, rolling, kicking, supported sitting, or weight-bearing through the arms and legs during play.

The goal isn’t perfection — and every baby develops at their own pace.

Rather, the goal is simply to provide babies with supportive, engaging opportunities to explore movement and interaction in ways that feel appropriate and manageable for them.

As pediatric occupational therapists, one of the things we think deeply about is how positioning, movement opportunities, and environment can influence a baby’s comfort, engagement, and ability to interact with the world around them during early development.

Small adjustments in positioning, play setup, and interaction can sometimes make movement experiences feel more comfortable, accessible, and enjoyable for babies and parents alike.

And while every baby’s developmental journey is unique, creating positive opportunities for movement, exploration, and engagement during supervised awake time can become an important part of everyday routines throughout infancy.

At Rahoo, we believe parents benefit from understanding not just what babies are doing developmentally, but how thoughtful positioning and interaction can help support those everyday experiences along the way.
