Narrator: and support his full weight of his body with his legs when being held upright.

Scene: The baby sits on the sofa and reaches out his hand to grasp a toy in front of him. He then picks up the toy and play with it. Another baby sits in his stoller playing with a toy. He explores the toy by passing it from one hand to another.

Narrator: He reaches out his hands to grasps toys, explores them with both hands, or passes them from one hand to the other.

Scene: The baby sits on his high chair carefully explores the toys in his hands. Another baby sits in his stroller and recognizes and looks at his mother and sister coming over to him from a distance.

Narrator: As for vision, your baby can fixate and follow small objects at near, and recognize familiar people readily at a distance.

Scene: The baby quickly turns his head to find his mother when he hears her calling his name from one side.

Narrator: As for hearing, he turns his head readily in response to a voice produced on either side.

Scene: The baby carefully examines and explores different parts of the toy in his hands.

Narrator: Considering his cognitive development, he continuously absorbs information from the surroundings and applies about it to his day-to-day activities.

Scene: The baby plays with a toy in his hand. He shakes it and hears some noise. He finds this interesting. He then repeats the same action repeated to make out more sounds.

Narrator: He also begins to grasp the concept of “cause and effect”. For example, shaking a rattle can make it sound. Realising that he can cause these interesting reactions, he will continue to experiment with other ways to make things happen.

Scene: The baby sits in his stroller is playing with a toy in his hands. The toy suddenly drops to the floor. The baby quickly follows and looks where it has fallen, and tries to reach for it. Another baby is playing hide-and-seek with his mother. He pulls down the towel to find his mother hiding behind it.

Narrator: Before then, your baby assumed that the things that he couldn’t see just didn’t exist, and would not bother looking for them. But now, he begins to acquire the concept of “object permanence”, realizing that things hidden do not vanish after all, he will try to look for them.

Scene: The mother plays with her baby in the sofa. The baby makes different sounds to express his feelings.

Narrator: Concerning his language development, he can distinguish your emotional tone of voice. He starts to make and imitate different sounds. However, the sounds produced in fact have no specific meanings.

Scene: The baby cries when she can’t see her mother around. She calms down quickly once her mother comes and picks her up. Another baby stands in front of a mirror. He is interested in his own image in the mirror and touches it with his hands.

Narrator: As for social development, your baby will start to develop anxiety towards strangers, but he shows great interested in his own image in the mirror.

Both nature and nurture affect every child’s development. While nature is important in determining your baby’s capabilities and abilities, the role of a nuturing environment is of equal importance in your baby’s learning and emotion development.

Development is a continuous process and has a certain sequence that children would go through. However, parents should remember that every child is unique. Children have their own pace in development and vary in their abilities. If you are unduly concerned, talk to your doctors or nurses.

What you can do

I am stronger in my physical ability

I want to play with you

When I am lying on my tummy, I can support my body with my forearm and lift up my head

Lay me on my tummy and call out my name. By raising my head to look at you, I can exercise my neck muscles

Spend altogether 30 minutes for such activity every day!

I also enjoy other physical activities with you, for example, play and attract me from either side so that I shall roll from side to side to find you

Apart from loving to touch, I like being touched, too!

I can see farther and clearer

Catch my eyes

I love looking at moving things. My sight can reach farther now. I can see you even if you are standing 1-2 metres (a few feet) away, and my eyes will follow you wherever you go


I am curious about my surroundings. Let me face outward when carrying me. When I am sitting in my baby chair, position me at where I can see you doing chores

My brain development is getting more complex

Encourage me to explore and testing out

I can integrate the senses mentioned above to learn about the world around me through different means. For example, if you place a rattle in front of me, I can reach out for it accurately. When I shake and mouth it, I will discover all of its properties such as it has sounds, it can be shaken, it is round and smooth etc

When I have lost interests or tired, please let me take a break

Are the toys of your baby safe?

As babies like to explore with their hands and mouth at this stage, parents should pay serious attention to toy safety.

So you think that pricey toys should be safer? There are many different toys available in the market, but parents should choose toys that are safe and facilitating babies’ development. As babies under 1 year old like putting toys into their mouth, parents should take into consideration the design and materials of toys when shopping for babies. Let’s learn how to pick the safest toys for our babies!

When choosing toys for your babies, you should bear in mind:

  • Rattles with small parts will be easily swallowed by babies and may lead to suffocation.
  • Pay attention to the safety labels on toys; make sure that the colours and paints used on the surface of toys comply with the safety standards. Colours that are not up to standard may contain heavy metal (e.g. lead). If children lick the colours constantly, they may suffer from chronic heavy metal poisoning.
  • Pick toys that are light in weight for babies. Do not pick the ones that are inflammable, fragile or rust easily.
  • Avoid stuffed toys. Stuffed toys are difficult to clean and they may lead to suffocation when covering the baby’s face.
  • The edges of toys have to be smooth. Check often to avoid any sharp edges or cracks hurting your baby.
  • Clean the toys frequently, as babies like dropping them onto the floor and putting them into their mouth.

All you need in your first-aid kit

Home accidents do happen. Babies are vulnerable and are dependent in protecting themselves. So parents need to exercise home safety precautions as well as knowing how to reduce the degree of the accidental injuries at home. Having a first-aid kit at home is essential to treat minor injuries. Parents should also equip yourselves with first-aid skills to protect your vulnerable baby in emergency. If the condition serious, consult a doctor as soon as possible.

A standard first-aid kit should contain:

  • Sterilized cotton
  • Sterilized gauze
  • Dressing Pad
  • Adhesive bandages
  • Elastic bandage (2″/5cm wide and 3″/7.5cm wide each)
  • 70% alcohol
  • Mild disinfectant
  • Safety pins
  • Round-ended scissors
  • Triangular bandage
  • Disposable gloves
