Sensory Learning: How a Baby Learns

Sensory Learning: How a Baby Learns

How your baby learns through her mouth—and how to encourage it.

Perhaps even more than adults, babies are engaging all of their senses as they grow and learn. As a parent, you can help encourage sensory learning through a variety of ways!

Of the five senses—hearing, seeing, smelling, tasting, and touching—parents are often most concerned with the first two. After all, doctors check to make sure your baby can see and hear well, and it’s easy to understand why these senses are important to how a baby learns. In reality, though, your baby collects data about the world in many sensory ways. 

Here are some examples of other forms of sensory learning along with tips for how you can help to enhance it:


The lips and tongue are more sensitive than the fingers during the first six months of life. That helps explain why your baby seems to bring everything she can—from your fingers to her board books—up to her mouth to lick, gum, suck, and drool on. These explorations provide the brain with volumes of information about an object: shape, texture, size, temperature, weight, and more.

What you can do:

  • Provide your baby with lots of safe toys and books of a size that he can lift to her mouth.
  • Look for toys (like rattles and plastic teethers) that feature a variety of surfaces, from smooth to bumpy, to familiarize her with a wide range of textures.
  • Try not to discourage her from bringing things to her mouth. Instead of saying “no,” simply remove objects that could be swallowed or are too sharp or otherwise potentially dangerous.

Tasting and Smelling 

The senses of taste and smell are highly interconnected. Your baby's first taste buds appear around the second or third month of the baby development stages, and she'll be able to smell around week 28. She quickly learns to identify your unique smell as a newborn, and a lot of her taste decisions later on will be influenced by the flavors she is experiencing in your prenatal diet. If you choose to nurse, your baby will recognize and be comforted by those flavors in your breast milk.

What you can do:

  • Notice whether your baby reacts to various smells. In general, babies tend to relax and smile more around sweet and milky scents (like breast milk or formula), and they kick their legs or cry at the scent of foul ones.
  • Try to be patient if your older baby rejects a food, like broccoli, because of its strong smell. Keep offering and trying new ways of preparing it, because it can take 5 to 10 exposures before a toddler will try new foods. A varied diet can help your child get all the nutrients needed.

Grabbing and Grasping

The ability to grasp a rattle or spoon starts at around 3 months. As your baby grows, reaching for objects is a way for her to bring them close enough to explore. For example, around 7 to 8 months, babies are learning about spatial relationships. Reaching for toys helps her understand concepts such as “top” and “bottom,” the shape, or what’s easy to grab (like a cup handle) versus what’s more difficult (such as a smooth, fat cylinder). By 10 to 11 months, your baby has figured out how to manipulate objects in specific ways, like poking fingers in holes or tearing paper.

What you can do:

  • Place interesting toys and other safe objects just out of reach, so your baby can practice reaching and holding.
  • Pay attention to age-appropriate labels on toys, which are specifically designed in ways that meet your baby’s developmental stage. Rather than introducing toys for older children in hopes that your baby will get a jump on the learning curve, be aware that toys that are too advanced can cause frustration or boredom.

Dropping and Throwing

Why do older babies like to drop spoons from high chairs or toss toys across the room? To see what happens! Does it make a sound? Where does it go? Hand-eye coordination and spatial awareness also develop this way.

What you can do: 

  • Don’t get mad when your baby drops toys or food. She’s just being curious and exploring the world via sensory learning.
  • Give your baby containers to put things into and take them out of, at around 12 months.
  • Around 18 months, introduce a soft ball your baby can toss or roll as a safe substitute for food or other household objects.
