Scientific evidence shows that with every meal, up to 75 per cent of the nutrients your child consumes contribute directly to brain development. More than 80 per cent of a child’s brain develops by the age of three.*

Every affectionate interaction—every hug, every nourishing meal, every playful exchange—stimulates brain growth and strengthens emotional and cognitive foundations for lifelong learning and wellbeing.

The following guidance outlines key stages in early childhood development and offers practical actions parents and caregivers can take to support their child’s healthy growth.


Caring for Your Newborn

Did you know?
Within days after birth, babies begin to smile in response to the smiles of those around them.

  • Provide opportunities for your baby to see, hear, move freely, and experience gentle physical contact. Early movement may appear uncoordinated, but it gradually develops into controlled motion.
  • Maintain eye contact and smile back at your baby. This positive exchange reinforces emotional bonding and helps your child recognise and interpret facial expressions.
  • Speak softly and respond to your baby’s cooing or babbling. Both parents and caregivers should engage in frequent verbal interaction; newborns begin to distinguish familiar voices and later attempt to imitate them.
  • Vary the tone and rhythm of your speech—alternate between softer and louder, slower and faster tones—and observe how your baby reacts. Such variations help stimulate auditory and emotional development.
  • Place your baby on their tummy and gently move a rattle or bell to encourage them to lift their head and shoulders. This strengthens neck and upper body muscles and develops visual tracking skills.
  • Comfort and hold your baby often. Gentle physical touch helps the infant feel secure, calm, and connected.
  • Skin-to-skin contact, hearing your voice and heartbeat, and recognising your scent all promote feelings of safety and attachment.

Caring for Your Baby: 1–6 Months

Did you know?
Infants between one and three months old see most clearly objects located approximately 20–30 centimetres away. By three months, their range of vision expands significantly.

  • Allow your baby to explore through sight, sound, touch, and movement. These sensory experiences foster trust and early emotional connection.
  • Move colourful objects slowly within your baby’s view to help them follow and reach. Simple toys, such as rattles, encourage sensory exploration.
  • Smile and laugh with your baby. Reciprocal smiling strengthens emotional communication.
  • Engage in “serve and return” interactions: respond to your baby’s sounds or gestures and imitate them. This process supports language development and social bonding.
  • Encourage visual tracking by slowly moving objects side to side and up and down.
  • Provide safe, lightweight objects for your baby to grasp, such as a soft cup or ring.
  • Display simple images of familiar people, animals, or objects. Use contrasting colours and varied textures, and describe what you see. The baby learns to associate words with objects and experiences.
  • Incorporate gentle play. For example, while your baby lies on their tummy, run your fingers along their back or lightly tickle their hands and feet. Such physical play enhances body awareness and bonding.

Caring for Your Baby: 6–9 Months

Did you know?
By six months of age, most babies can safely eat a variety of foods—except honey, which should be avoided until after the first year.

  • When communicating, pause and allow your baby time to respond. Counting silently to ten can help. If there is no reaction, model an appropriate response and try again with simpler language.
  • Use your baby’s name frequently to reinforce recognition and attention.
  • Speak and sing in a calm, gentle tone. Loud or abrupt sounds can cause distress.
  • Smile often. Consistent positive expression helps your baby feel secure.
  • Offer safe, clean, and colourful household objects—such as wooden spoons or plastic bowls—for exploration and play.
  • Use picture books, soft puzzles, or puppets to nurture curiosity. Homemade materials, such as pictures mounted on cardboard, can be effective for learning and discovery.

Caring for Your Baby: 9–12 Months

Did you know?
Babies take great delight in seeing that their actions bring joy to those around them.

  • Encourage your baby to place objects into a container and remove them again. This promotes hand–eye coordination and problem-solving skills.
  • Provide opportunities to stack blocks or similar objects. These activities foster spatial awareness and fine motor development.
  • Ask simple questions and respond to your baby’s attempts at speech. Early conversations support language growth.
  • Talk about your surroundings—nature, people, and familiar objects. Curiosity about the environment signals readiness for exploration.
  • Describe what your baby is doing: “You are filling the box.” Naming actions reinforces understanding and builds self-confidence.
  • Offer to help: “Let’s do it together.” Cooperative play strengthens trust and emotional regulation.
  • Use daily routines, such as feeding or bathing, as opportunities for dialogue. Over time, your baby will understand simple instructions and begin to respond.
  • Turn questions into playful interactions: “Where is your toe?” or “Where is the bird?” Looking at pictures and naming objects stimulates communication and curiosity.

Caring for Your Child: Two Years and Beyond

Did you know?
Children learn positive behaviour more effectively when they are shown what to do rather than when they are punished for mistakes.

  • Ask simple questions and actively listen to the answers. Encourage conversation by prompting: “What is this?”, “Where is the window?”, or “Which ball is bigger?”. Engaged dialogue nurtures language and reasoning skills.
  • Read aloud regularly. Ask questions about the story or pictures and encourage your child to describe what they see. Storytelling enhances vocabulary and memory.
  • Introduce basic counting by asking “How many?” and counting everyday objects together. Repetition helps strengthen early numeracy.
  • Provide shapes—circles, squares, triangles—cut from coloured paper and invite your child to compare, sort, and match them. Such activities develop categorisation, pattern recognition, and early problem-solving.
