The Sensory Baby: Why Mess Matters at Every Stage of the Day

A guest post by Amy, Founder of Good Bubble. Good Bubble make joyful, safe and planet-friendly bathtime products for babies and children, including award-winning collaborations with The Gruffalo & Friends and Peppa Pig.

At a glance: 

From their first taste to their last splash of the day, babies are wired to learn through their senses. In this post, we explore the developmental science behind sensory play and why embracing the mess, at mealtimes and bathtime alike, is one of the most powerful things you can do for your baby.

What Is Sensory Play, and Why Does It Matter?

Sensory play is any activity that stimulates one or more of a baby's senses - touch, taste, smell, sight, sound and proprioception (the sense of body position). Far from being incidental fun, sensory experiences are the primary driver of early brain development.

Every time a baby squishes a piece of banana, splashes in a puddle or runs their fingers through a pile of peas, billions of neural connections are being formed and reinforced. Research published in Frontiers in Psychology highlights that hands-on, multi-sensory experiences in infancy are closely linked to advances in fine motor skills, language acquisition, emotional regulation and problem-solving ability.

The key word here is exploration - and exploration is inherently messy.

The Developmental Stages of Sensory Learning

Understanding how babies process sensory information at each stage helps parents appreciate why the mess isn't there purely to cause chaos, it’s crucial for learning.

0–6 Months: Passive Sensing

In the earliest months, babies are primarily receivers. They observe contrasting colours, respond to your voice, root for texture and are calmed by warmth. Bathtime at this stage is already a full sensory event - the warmth of the water, the gentle sound of splashing, the scent of a mild wash, the feel of your hands… and it lays the neurological groundwork for active exploration to come.

6–12 Months: Active Exploration Begins

This is when things get interesting (and more messy!) Babies begin reaching, grasping, mouthing and banging. It’s also when weaning typically begins, and with it comes one of the richest sensory learning opportunities in early childhood.

That’s why we love Tidy Tot products like the Bib & Tray Kit system, which are designed not to eliminate mess, but to contain it giving babies the freedom to touch, squish, and explore their food without parents dreading the aftermath or cleaning a far-reaching splatter zone! That freedom is developmentally crucial. When babies are allowed to self-feed and play with their food, they develop a healthier relationship with new textures, reduce food neophobia (fear of new foods) and build the pincer grip that underpins early writing.

12–18 Months: Cause and Effect

Now babies are deliberate, and they drop things to watch them fall. They pour water from cup to cup. They press, poke, and prod with intention. Causality is the scientific concept being explored here and it is one of the building blocks of logical thinking.

Water play, whether in the bath or with a simple washing-up bowl, is ideal for this stage. Pouring, splashing, and watching objects float or sink introduces early physics concepts in the most natural way possible. A bathtime that allows unhurried splashing and pouring is doing far more than getting a baby clean.

18 Months–2 Years: Sensory Play Becomes Symbolic

Toddlers begin using sensory materials more creatively; mud becomes a cake, bath foam becomes a mountain, a bowl of pasta becomes "dinner for teddy" This is the emergence of imaginative play, and it is powered by sensory confidence built up over months of exploratory mess.

The Five Richest Sensory Experiences in a Baby's Day

1. Mealtimes
Few daily routines offer the sensory richness of mealtimes. Different temperatures, textures, smells, and colours - all combined with the social experience of eating together. 

2. Outdoor Play
Grass, soil, sand and leaves offer a range of tactile stimulation. Research consistently shows that children who play outdoors regularly have lower cortisol levels (a marker of stress) and stronger immune systems. Getting dirty outside is quite literally good for health.

3. Sensory Trays
A simple tray filled with dry rice, cooked pasta, or kinetic sand offers a low-cost, parent-controlled sensory environment. These can be introduced from around six months (with appropriate supervision) and adapted as the child grows.

4. Music and Movement
Sound is a sensory input too and often underestimated. Singing, dancing, rhythm instruments, and even everyday sounds like rain on windows or the hiss of a kettle stimulate the auditory cortex and support language development. Singing nursery rhymes with my nearly 2-year old daughter is quite literally one of my favourite things to do!

5. Bathtime
Bathtime is arguably the most multi-sensory routine in a baby's day and it really is worth running the tap for. 

• Touch: Water temperature, the drag of water against skin, the squishiness of a rubber toy, the smoothness of a plastic cup
• Proprioception: The feeling of weightlessness in water, reaching and stretching in a different physical environment
  
• Sight: Reflections, bubbles, floating objects – and maybe a bottle with their favourite story time character! 
  
• Sound: The sound of running water, splashing, your voice echoing slightly differently
  
• Cause and effect: Splashing creates ripples; squeezing a toy produces a stream of water; pouring empties and fills.

This is where Good Bubble comes in. Our clinically tested, paediatrician approved and clean-ingredient formulations are formulated specifically for young and delicate skin. With super-soft foamy bubbles and beautifully scented, allergen-free fragrances. Did we mention the oxytocin kick from a post bathtime snuggle in the towel? ♥︎

Why "Mess Tolerance" Is a Parenting Skill Worth Developing

One of the biggest barriers to sensory play isn't product or space - it's parental anxiety about mess. And, trust me, I get it. 

But childhood development studies consistently link messy, adventurous and risky play as hugely beneficial for little ones. In fact, the EYFS Primary Framework by the UK government directly names messy play as supporting problem-solving, cause and effect, fine motor skills, counting, and communication. 

The good news is that mess tolerance doesn't mean abandoning all structure. It means choosing the right tools. Tidy Tot's approach at mealtimes and Good Bubble's approach at bathtime, reflects the same underlying belief: that the right product creates the conditions for exploration without the dread. A contained, well-designed environment lets babies do what their brains are demanding, while keeping parents sane.

Practical tips for mess-friendly parents:

• Use a splatter mat (or Tidy Tot’s Bib & Tray Kit) to reduce clean-up
  
• Keep a dedicated "messy kit" - clothes, bibs, and a wipeable tray - so sensory meals feel less daunting
  
• Lean into the bath as your sensory session of the day; the least messy part of the day - just have towels ready to soak up the splash zone!
  
• Narrate the mess: "You're squishing the banana, it feels squishy doesn't it?" helps turn sensory play into language learning at the same time AND verbalising the messy event also helps to regulate our own stress-levels about said mess. 

The Sensory Day: A Simple Framework

Rather than thinking of sensory play as a separate activity to schedule in, try thinking of your existing daily routines as sensory opportunities:

Breaking up the day like this helps to show that sensory-rich days often occur naturally anyway and rather than requiring loads of extra effort, it just take a small shift in perspective and a willingness to fully embrace. Remember, you’re building a brain here. You got this! 

Frequently Asked Questions

At what age can I start sensory play with my baby? Sensory play begins from birth -every cuddle, every song, every warm bath is sensory. More structured activities like sensory trays can be introduced safely from around six months, always with supervision.

Is it safe for babies to play with food? Yes - for babies who have been cleared to start weaning, food play is not only safe but developmentally encouraged. Ensure babies are seated upright and supervised. Avoid foods that pose choking risks for the developmental stage.

How long should a sensory bath session last? Even 10–15 minutes of unhurried bathtime with opportunity for splashing, pouring, and exploring is developmentally rich. There's no minimum or maximum - follow your baby's cues.

Do babies need expensive sensory toys? No. Some of the richest sensory experiences come from everyday household objects: wooden spoons, measuring cups, dry pasta and warm water. What matters most is freedom to explore and products that make the environment safe and enjoyable. Good Bubble's range is designed to do exactly that at bathtime, without compromising on ingredients.

What is the link between sensory play and speech development? When parents narrate sensory play describing textures, temperatures, and actions they dramatically increase the number of words babies are exposed to. Studies show that this kind of language-rich sensory interaction significantly boosts vocabulary development by age two.

The Takeaway

Mess is development. The squished peas, the splashed bathwater and the hands coated in yoghurt: these are not problems to be eliminated but signals that your baby is doing everything their brain needs them to do.

By leaning into the sensory opportunities already built into your day, with a little help from the right tools, you're not just surviving the mess. You're actually building a real-life brain. Amazing.
