Your Baby at 2 Months: Sensory Development Explained

Something shifts at around two months. You might have felt it already - your baby is suddenly more present. More alert. More interested. They’re looking at you differently. They’re responding.

This is the sensory system coming online. And what’s happening right now - in ways most parents have no idea about - is directly connected to how your baby will approach food in four months’ time.

Here’s what’s going on, and why it matters.

 

Two-month milestones: what’s happening right now

According to NHS guidance, here’s what you’d typically expect to see at around eight weeks:

• The social smile appears - your baby smiles in response to your face or voice, not just wind
• Vision is sharpening - focuses at 20–30cm, tracks moving objects more smoothly
• Face recognition - can distinguish between different faces, especially the primary caregiver’s
• Vocalisations increase - coos, gurgles, begins responding to conversation
• More time alert and awake - more periods of engaged wakefulness each day

Your baby’s vision at 2 months - and why your face matters most

At two months, your baby’s visual world is expanding. They can now track a moving object relatively smoothly, focus at the distance of your face during a feed, and are beginning to tell faces apart.

The NHS notes that babies at this stage are particularly drawn to high contrast and - above all - human faces. Your face isn’t just comforting to your baby. It is literally the most visually compelling thing in their environment.

This matters for feeding for a reason you might not expect: visual attention is the first component of the see-reach-grasp sequence that eventually becomes self-feeding. The careful visual tracking your baby is practising now - following your face, following movement - is the same neural pathway they’ll use to look at a piece of food, reach for it, and bring it to their mouth.

It starts with watching your face. It ends with using a spoon. The distance between those two things is smaller than it looks.

 

Why babies put everything in their mouth (it’s not what you think)

If your baby has started bringing their hands to their mouth - or grabbing anything within reach and attempting to eat it - you might be tempted to see this as something to manage.

Don’t. It’s one of the most important things they’re doing right now.

Mouthing is how babies under six months explore texture, shape and sensation. The mouth is, at this stage, more information-rich than the fingertips. When your baby mouths their fist or a toy, they’re building what’s called oral motor development - the coordination of the lips, tongue and jaw that will later be essential for managing solid food.

How smell and taste are already more developed than you’d expect

Here’s the finding that surprises most parents: your baby’s sense of smell and taste has been developing since before birth. And if you’re breastfeeding, it’s still developing now - through you.

Research by flavour scientist Julie Mennella and colleagues - well-established and widely cited in infant feeding literature - has shown that flavours from the maternal diet pass through breast milk. Babies exposed to a varied range of flavours through breast milk show greater acceptance of those same flavours when introduced as solid foods.

In other words: the garlic in your pasta tonight may make your baby more receptive to garlic when they try food for the first time at six months. The NHS also notes that taste preferences begin forming during this period through breastfeeding.

If you’re formula feeding, your baby is still developing taste preferences - just through a slightly different route. What matters is what comes next: varied, flavourful food from the start of weaning.

 

Touch, texture and sensory learning at 2 months

Your baby’s skin is exquisitely sensitive - far more so than an adult’s. At two months, touch is one of their primary ways of understanding the world. The weight of your hand, the texture of a muslin cloth, the difference between a firm surface and a soft one - all of this is data.

This tactile sensitivity is the foundation of texture tolerance. The babies who are most comfortable with different textures in their hands at two months tend to be the babies who are most comfortable with different textures in their mouths at six months. It’s the same sensory system, applied to a new context.

You’re already supporting this every time you let your baby feel different fabrics, surfaces and temperatures - even if you didn’t know that’s what you were doing.

The sensory-to-weaning connection: why this all matters later

Everything described above - visual tracking, mouthing, flavour exposure through breast milk, tactile exploration - is building the sensory foundation that determines how open your baby will be to new foods at six months.

Weaning readiness doesn’t start at six months. It starts now.

At doddl, we’ve spent 7 years working with paediatric occupational therapists, Norland College, and the University of Exeter to understand the full developmental arc from first feed to first spoon. One of the most consistent findings from that work is that sensory development in the first few months is not a precursor to weaning — it’s the beginning of it.

The sensory experiences your baby is having today are building their relationship with food. You’re already preparing them for weaning without realising it.

Our partner Fundamentally Children - one of the UK’s leading authorities on early childhood development and a doddl endorser - recognises early sensory experience as central to the development of food acceptance. This is the science that informs everything we do.

Simple things you can do right now to support sensory development

You don’t need a programme or a special kit. These are everyday interactions that build the sensory foundations described above:

• Vary your diet if breastfeeding - research suggests this exposure supports later food acceptance
• Let them mouth safely - age-appropriate teethers and toys with varied textures all count
• Use tummy time on different surfaces - carpet, playmat, your chest - varied tactile input is valuable
• Talk about what you’re eating - even now, your baby is watching and listening when you eat. This is their first model of mealtimes
• Describe textures and flavours out loud - ‘smooth’, ‘crunchy’, ‘sweet’ - the language of food is being absorbed long before the food itself arrives
