The blossoming of senses and curiosity.
Between the fourth and sixth month, your child gradually leaves the newborn world to become an active explorer. It is time for the first taste discoveries and voluntary movements.
A transition towards autonomy
In 2026, we understand better than ever that this period is not simply waiting for the "first steps," but a crucial phase of neurological structuring. Archaic reflexes fade away to give way to intentional fine and global motor skills. It's a journey where each day brings a nuance of a look, a new sound, or a deeper interaction.
Social Interactions
Laughter becomes intentional. Baby recognizes familiar faces and expresses joy with their whole body.
Cognitive Curiosity
Exploration happens through the mouth and hands. The concept of object permanence begins to emerge.
Table Pleasures
Food diversification introduces a world of new colors, tastes, and textures.
The symphony of movement
At 4 months, your baby has acquired excellent tone in the head and upper trunk. This is when they start to "pivot" on their stomach, like a small compass needle looking for toys. Between 5 and 6 months, muscle strength shifts towards the lower back and hips.
- ● Rolling over: Moving from back to front (often accidental at first, then mastered).
- ● The sitting position: Baby can sit with support, their back rounding less.
- ● Palmar grasp: They grab objects with the whole palm, a prelude to fine motor skills.
The adventure of first flavors
Food diversification (between 4 and 6 full months) is a window of metabolic and sensory opportunity.
The awakening vegetable garden
Start with smooth purees of "sweet" vegetables: carrots, squash, parsnips, or green beans. One vegetable at a time to identify any reactions.
Tip: No salt added.
Natural sweetness
After a few days of vegetables, introduce cooked fruits in a fine compote: apple, pear, mashed banana, or peach. Avoid sugar.
The sweet taste is innate, the salty one is learned.Allergens: Did you know?
Current recommendations (2026) advocate for an early and regular introduction of major allergens (peanuts, eggs, gluten) from 4-6 months, in an adapted form, to promote the child's immune tolerance.

The beginnings of dialogue
Your baby is starting to understand that their sounds have power over their environment. Marginal babbling appears: chains of sounds like "ba-ba" or "ga-ga". This is the very essence of the art of language.
Laughter out loud, shouts of joy, and modulation of the voice.
Responding to their name, imitation of tones and expressions.
Tip: Reformulate their sounds. If they say "Ba", answer "Yes, a ball!". You validate their communication and enrich their passive lexicon.
Inspiration for daily awakening
Simple, sensory, and safe games to accompany their growth.
The Magic Mirror
Promotes self-recognition and facial expression. Essential for awakening the senses.
Bubble Chase
Stimulates eye-hand coordination and visual tracking of moving objects.
The Treasure Basket
Objects of different textures (silk, wood, cotton) to develop fine touch.
Shared Reading
Even if baby doesn't understand the story, the rhythm of your voice is an auditory caress.
Sleep and Rhythms
Around 4-5 months, many parents observe a "regression" in sleep. In reality, it is a maturation: the child's brain is reorganizing its sleep cycles to look more like those of an adult.
At 6 months, naps often follow a rhythm of three per day (morning, early afternoon, end of day). This is also the period when nutritional needs increase, which can sometimes disturb nights if diversification does not yet compensate for energy expenditure.
Routine, your best ally
A bath, a soft song, or a massage create reassuring points of reference. Consistency in the environment (temperature between 18 and 20°C, darkness) helps baby secrete the melatonin necessary for falling asleep.
Frequently Asked Questions (4-6 months)
My baby is not rolling over yet at 5 months, is this normal?
Absolutely. Every child follows their own growth calendar. Some babies focus on vocal communication or fine motor skills before mastering rolling over. Consult if you notice overall hypotonia.
Can I give water to my baby?
With the start of diversification, you can offer a few sips of flat water (low mineral content) during meals. However, milk (breast or formula) remains their main source of hydration.
What are the signs they are ready for solids?
They hold their head well, they show interest in your plate, and they have lost the extrusion reflex (pushing the tongue out as soon as an object enters their mouth).
