The Fourth Month of a Baby’s Life: Sociability Flourishes
Now a stage of “independence” begins for your child. During a baby’s fourth month of life, he will learn to use his hands to pick up objects and will connect even more with his surroundings.
Many stutters and smiles are to come!
After the first trimester of life, a baby can begin to make more use of his body, as his muscles reach a new point in their development.
You’ll see him try to achieve new positions, such as sitting down, although he’s still not able to. But he can support himself on his arms while laying down in order to raise his head. He will also love to toss and turn in bed.
With that in mind, be very careful not to leave your baby alone on a high surface. He doesn’t know the dangers and limitations of certain actions just yet.
You’ll also notice that your baby becomes more attentive and interactive with his surroundings.
He’ll enjoy playing with toys (especially those that make noise), will put any object he finds in his mouth, and will babble and wait for a response from the person near him.
Be careful with his tendency to put objects in his mouth. Try not to leave anything he could choke on within reach.
As for his sociability, he will learn to laugh loudly when he is in a good mood and with the right company. He may cry when someone other than his mother or father approaches him, but this is only until he learns to trust them.
Body changes in the fourth month of life
- Weight gain slows down. He will gain about 150 grams per week.
- His height won’t increase greatly, either. Unlike what happened for the first three months, he will grow between 6 and 7 centimeters at this stage.
- Nighttime will be defined. He will sleep between 8 and 10 hours at night and will also take naps during the day.
- Fewer diapers to change, because he will have fewer bowel movements and will urinate less frequently.
- Better coordination of arms and legs. He can pick up objects but not make a pincer with his fingers. He will start trying to stand up on firm surfaces.
- Greater sociability. He will not like being alone. He will make his first sounds and even some syllables. He will smile much more and even produce laughter.
- Feeding does not change. Breast milk should continue to be the exclusive food source for the baby. Solid foods are incorporated only after 6 months of age.
- He will develop his vision in color. In addition, he can distinguish the faces of his parents and closest friends.
- The ear is optimized at this stage. He will begin to identify the voices of those who spend more time with him, especially his parents.
- There may be some discomfort. If the baby is irritable for some reason, such as constipation, nausea, cramps, diarrhea or a cold, consult with your pediatrician.
Advice for stimulation and growth
Your baby is the perfect age to have his senses stimulated. How do you do this? First, by providing toys that make noise or light up and react to your baby’s actions. In this way, your baby will begin to relate his actions with possible consequences.
During the fourth month of a baby’s life, an important cognitive development takes place. Put him in front of the mirror and repeat his name, so he can establish the connection.
Also, answer him whenever he speaks to you in order to encourage his ability to interact with others, and take him out for walks so he knows the outside world.
It is also important that you talk, sing or read to him. Change your tone of voice so he learns to interpret moods.
At all times, it is important that the baby has the ability to move, manipulate objects and learn to coordinate his actions on his own.
A highly recommended game for a baby’s fourth month of life is to lie him on his back and, facing him, offer a toy (preferably a brightly colored one) so that he must move up or to one side to reach it.
This exercise offers two fundamental benefits:
- It improves his flexibility and abdominal strength, as he must raise his upper limbs against the force of gravity.
- He develops his visual, tactile and auditory abilities.
As we always say, keep the vaccination schedule in mind and follow it to the letter.
Whether or not you should use a pacifier is a frequently discussed topic. It has its advantages, since it decreases the baby’s anxiety, but it can be counterproductive. You can find some advice on the subject in this article.
If you detect any abnormality or if your baby has any discomfort, do not hesitate to consult a professional. Otherwise, enjoy this stage. It will fly by!
