11 Montessori Activities for 6-12 Month Olds (Easy DIY)
Before I had my own tiny human, I had visions of being the ultimate Montessori mom. You know the type: a perfectly curated wooden playroom, neutral-toned outfits, and a child who calmly explores silk scarves. My baby’s favorite “toy” is the crinkly plastic wrapper from my granola bar.
If you’re currently staring at a mountain of expensive plastic toys that your 8-month-old ignores in favor of the TV remote, we need to talk. We are reclaiming the “Explosion of the Hand” with low-prep Montessori activities for your baby that actually use stuff you already have in your kitchen or junk drawer. No $200 subscription boxes required.
Baby Development Milestones
From a medical perspective, the window between 6 and 12 months is absolutely fascinating. Your baby is moving from the “Palmar Grasp”—where they clumsily grab things with their whole palm—to the “Refined Pincer Grasp,” which involves using the thumb and index finger like a seasoned pro.
Encouraging these baby development milestones through play isn’t just about keeping them busy; it’s about building the neural pathways for everything from self-feeding to eventually holding a pencil. As a doctor, I see these as the foundational blocks of motor function. As a mom, I see them as a way to get 10 minutes to drink a coffee while it’s actually hot. It’s about merging clinical benefits with the reality of a messy living room.
11 Easy DIY Montessori Activities
The High-Chair Tape Peel

This is the “Old Reliable” of the parenting world, and for good reason. You’ve probably seen a version of this somewhere, but the medical magic is actually in the frustration it creates. All you need to do is stick some colorful painters’ tape or masking tape onto the high chair tray. To make it “baby-accessible,” fold one tiny edge over to create a “tab” so they have a fighting chance at grabbing it.
You are essentially tricking your baby into a high-intensity finger workout. If they get frustrated, try to resist the urge to jump in immediately. That “struggle” is exactly where the brain growth happens.
Just ensure you’re using paper-based tape so if they do manage to sneak a piece into their mouth, it’s not a medical catastrophe.
The Rainbow Pom-Pom Whisk

If you have a kitchen whisk and a bag of craft pom-poms, you have a high-level developmental tool sitting in your utensil drawer. Simply stuff those colorful pom-poms inside the whisk and hand it over. To a baby, it looks like a strange, fuzzy colorful bird, and it serves as a complex puzzle that needs solving.
This is one of the most effective pincer grasp activities you can provide at home. They have to poke, pull, and wiggle those fuzzy balls out through the metal wires, which requires a surprising amount of finger strength and coordination.
From a safety standpoint, always use the large 1-inch pom-poms. I’ve seen enough “foreign body in nose” cases to last a lifetime, so please supervise this one closely to ensure nothing ends up as a mid-morning snack.
Edible “Oat Sand” Sensory Bin

We’ve all seen those beautiful, aesthetic sand sensory bins on social media, but 9-month-olds eat everything they touch. Real sand is a nightmare for diaper changes later and a choking hazard now.
Instead, whiz some dry breakfast oats in a blender until they look like fine sand. Pour it into a shallow bin, throw in some 90s-style wooden animals or spoons, and let them go wild.
This provides all the tactile exploration of a sandbox without the “emergency room visit” if they take a curious bite. It’s a “clean” kind of messy that you can easily vacuum up later. Interestingly, this pairs perfectly with my guide on What to Feed a 6-Month-Old Baby—once they’ve finished exploring the texture of the oats with their hands, they are much more likely to accept different textures during mealtime.
The DIY Tugging Box

Don’t throw away that diaper box! It’s about to become the most engaging toy in your house, and it cost you exactly zero dollars. Use a pair of scissors to poke holes in a cardboard box, then thread different ribbons through—think velvet, silk, and grosgrain—and tie big knots on the ends so they can’t be pulled all the way out.
As your baby pulls one side of the ribbon and watches the other side disappear, they are learning a hilarious and vital lesson in cause and effect. This is fantastic for “Gross Motor” strength because they aren’t just using their fingers; they’re using their whole arm and core to yank those ribbons.
The “Squeeze & Splash” Sponge Play

Water play is the ultimate sensory experience, and it’s the only thing that stops the “witching hour” in my house. You just need a shallow tub of water and a few clean, colorful kitchen sponges. Show your baby how to dunk the sponge, watch it get heavy, and then squeeze the water back out.
This activity is a powerhouse for “Proprioceptive Input,” helping your baby understand the strength and resistance of their own hands. It’s a physical therapy session disguised as a bath.
Plus, a good sensory session usually leads to a much better nap. If you’re struggling with the afternoon slump, check out my tips on Safe Sleep for Baby to help bridge that gap between high-energy play and restorative rest.
The No-Mess “Stained Glass” Paint Bag

If you want the “artistic” vibes without the “I need to repaint my walls” consequences, this TikTok-viral hack is your new best friend. Squirt a few blobs of primary color paint into a heavy-duty Ziploc bag, then tape it securely to a window where the sun shines through, or flat to the floor for some tummy time.
As your baby squishes the paint around, they can watch the colors mix into greens and purples right before their eyes. If you want to get fancy, add a spoonful of baby oil and some flat pearls or sequins; it creates a “liquid motion” effect that is hypnotic for an 8-month-old.
This is my secret weapon for babies who hate tummy time. If they’re distracted by the “magic” colors mixing under their fingers, they forget they’re actually doing a baby workout for their neck and shoulder muscles.
The Vertical “Sticky Wall”

Once your baby starts “cruising”—shoutout to those of you currently being used as human furniture—they need vertical play to stay upright and engaged. Tape a piece of contact paper, sticky side out, to the wall or a low kitchen cabinet. Then, simply stick lightweight felt shapes, ribbons, or even large leaves from the garden to the surface.
Reaching up and pulling things off builds incredible shoulder stability and core strength. It’s essentially “Baby CrossFit” but with felt rainbows. Furthermore, reaching across their midline—moving the right hand to the left side of the wall—is a huge neurological milestone that helps coordinate the two hemispheres of the brain. It’s a simple setup with massive long-term benefits.
The Tissue Box “Post-Box”

Spatial awareness is a big milestone around the 10-month mark, as babies start realizing that objects can exist inside other objects. Grab an empty, colorful tissue box and some old coasters or large, thick playing cards. Show them how to “post” the cards into the slot and listen for the satisfying “thump” as it hits the bottom.
This is a budget-friendly version of the classic Montessori Object Permanence box. If you find your baby is more interested in ripping the box apart than posting the cards, don’t sweat it. This is totally normal developmental behavior!
The Spice Jar “Smell & See”

We often forget about the sense of smell in baby play, but I love this because it connects the olfactory system directly to memory and emotion. Clean out a few old spice jars and fill them with whole cinnamon sticks, dried lavender, or even fresh lemon peels. Most importantly, glue those lids shut tight so they can’t be opened.
Your baby can see the interesting textures through the glass and catch the scents through the small shaker holes. It’s a sophisticated sensory experience that doesn’t involve a single battery or flashing light.
If you’re worried about your baby becoming a “Picky Toddler,” exposing them to different aromatic scents early is a great strategy. Check out my 12 Power Foods to Prevent a Picky Toddler for more on building a “brave eater” through sensory exposure.
The Cookie Sheet Magnet Tray

Physics for babies is much simpler than it sounds. Take a metal baking tray and some chunky, oversized magnets—I usually suggest the big animal or vehicle sets that are one solid piece. Letting your baby slide the magnets across the tray teaches them about resistance, magnetic pull, and spatial arrangement.
It’s a very satisfying tactile feeling for a baby who is just learning how to manipulate their environment.
However, a quick medical warning: ensure the magnets are large and well-constructed. If a magnet pops out of its plastic casing, it becomes a major medical emergency if swallowed. Use the “Toilet Paper Roll” test—if it fits through the cardboard hole, it’s too small for your baby to play with unsupervised!
The Colander “Porcupine”

This is the king of low-prep sensory play. It requires an intense level of focus and usually results in a very quiet, concentrated baby. Flip a kitchen colander upside down and hand your baby a few fuzzy pipe cleaners. Show them how to thread the pipe cleaners into the tiny holes, creating a colorful “porcupine” effect.
This activity promotes “Hand-Eye Coordination” better than almost any store-bought toy I’ve seen in the pediatrician’s office. It requires them to align their visual field with their motor movements in a very precise way.
Montessori Activities For Baby are Easier Than You Think
You don’t need to spend a fortune or have a PhD in Early Childhood Education to let your baby explore Montessori activities. Most of the time, your baby just wants to do what you are doing. If you’re using a whisk, they want a whisk.
Most often times, complex systems are often built on the simplest foundations, and your baby’s brain is no different. Give them some tape, a cardboard box, and a few sponges, and watch them build their world.
I’d love to hear from you! Which of these activities did your baby actually enjoy, and which one did they just try to launch across the room? Drop a comment below and let’s chat!
