The baby of 4 months

O bebê de 4 meses

Many changes happen in the baby’s 4 months. He’s much firmer, pays more attention to things, vocalizes new sounds and recognizes when they call him by name.

The interactions and stimuli are very responsive and he already explores the possibilities of all the senses, with the sense of smell, hearing and taste being developed in the womb.



The vision gets better and he can see colors, which makes the toys and things around him much more attractive.

Research at the Massachusetts Institute of Technology showed that the visual cortex of the brain of a 4-month-old baby and an adult has the same structural organization, so your baby recognizes faces, objects and situations.

To stimulate and develop this sense, keep betting on mobiles, place colorful toys next to him, show pictures and images and during the tour, draw his attention to everything he can see.

Another fun stimulus is to place the baby in front of a mirror. The joke is on account of you also appearing in the reflection and hiding.



The touch is more evolved and with greater sensitivity. The baby uses his hands more and is already able to reach his arms to pick up the objects around him or those that are offered, although he does not have much strength to do so.

The way they prefer to explore these objects is by taking them to the mouth. Therefore, avoid offering keys, for example, as they pass through various places, becoming full of microorganisms harmful to the baby.

He also finds his feet. If it doesn’t happen right away, show it to them when they’re playing together.

To stimulate this sense, offer objects with different textures. Children’s rugs with pendants and places to squeeze or explore, which make noises when touched, are great for discoveries.


Hearing and Language

The baby listens very well since pregnancy. At 4 months, he recognizes his own name and turns to look when he is called.

It makes a greater variety of sounds, with little squeaks when you hear your voice. And the most beautiful part of this phase: some babies start to laugh out loud. Those that enchant in videos on the internet. If yours is a little more serious, don’t worry, keep playing and stimulating reactions, that when you least expect it, they will be laughing together.

Always talk to your baby a lot. Repeat the sounds it makes and show images that reproduce sounds.


Firmer movements, heightened attention

He has a firmer waist. When held upright, it can sustain the trunk for a short time. Do this exercise for a few minutes. It will assist in strengthening and developing the vision, which will be explored.

He starts to turn face down alone. Reduce your attention and never leave your baby alone on the bed, op , changing table or any other high place to avoid falls and serious op lace.

The recommended place is on top of a soft blanket on the floor. He will play a lot and safely. If you are elsewhere, op la under supervision.


It op lac possible op lace the baby seated at a 45 ° angle with the support of a pillow and if it is in the stroller, do not forget the belt.



It is the turn of the 2nd dose of the following vaccines:

– Pentavalent, which protects against diphtheria, tetanus, whooping cough, hepatitis and meningitis B;

A few months of waiting will make a difference in the baby’s health, reducing the risk of allergic reactions.

Since he is more active, any distraction will make him stop breastfeeding to see what happens. A tip is, if you can, breastfeed in a quieter place.


Time to get back to work
