Baby development: what should your 3 month old baby be able to do

A 3-month-old baby already stays awake longer and cares about what is around her. They are able to turn their head towards a sound, smile, look and shout spontaneously, to arouse the attention of adults. In addition, their facial expressions can indicate joy, pleasure, indecision, anxiety and pain.

It is from this stage that the first tears appear, because the tear glands of the baby finally begin to function. Often the mother's voice is the baby's favorite sound and is the best way to calm the baby down when they are crying because it means warmth, comfort, and food.

His vision is more accurate and uses it to relate to those around him, participating more in the home, babbling, smiling and looking at people. Besides, if the baby is in his room he is able to look for his mother.

3 month old baby's sleep pattern

A 3 month old baby begins to regulate their sleep pattern at this stage. Their internal clock begins to synchronize with the world around them, being able to identify the difference in sleep during the day and at night.

At this age, the baby sleeps a little less, on average 15 hours a day. Many may sleep through the night, however, those who are exclusively breastfed may still need to wake up every 3 hours to breastfeed.

Diapers should be changed whenever the baby does poop, as this ultimately disturbs your sleep, but you should avoid doing these changes at night so that the sleep is not interrupted.

Your 3-Month-Old Baby’s Development

The 3-month-old is able to raise their head and control it when he is on his stomach and is also able to fix his gaze, showing preference for some objects and people. In addition, he can also smile in response to a gesture or the words of an adult, being more interactive.

In this phase, there also begins to appear more spontaneous movements, that are less abrupt and impulsive than those of the first and second month. Usually they are more slow and repeated movements, being possible to notice that the baby is paying attention to the way they happen and how he manages to control its own body.

As for the hearing and vision, the baby can already combine both senses, because in case of a noise, he is able to raise his head and look around, looking for its origin. The vision becomes clearer as well, so you begin to use it more to relate to those around you, babbling, smiling, and looking at people. In relation to the language, he begins to make his first sounds, stammering the vowels A, E and O.

In some cases, the baby may have some strabismus, it seems that the eyes are squinting, but this tends to happen at this stage because they do not have total control of the muscles of the eyes. However, it is important to always be aware of the baby's reactions to the stimuli that are shown to him, since it is from this age that more serious problems can be diagnosed such as a hearing deficit for example.

What are the best games for a 3 month old baby

Playtime for a 3 month old baby can be useful to stimulate and increase the bond with the baby, being recommended that parents at this age:

  • Let the baby take his hand to his mouth so he starts to get interested in picking up objects. You can start with your hand closed, but over time the tendency is to open it to hit objects above his head;
  • Offer teethers and other vibrantly colored instruments;
  • Lay the baby belly down, and stand in front of him waving a toy on a higher level to encourage him to lift his head and trunk higher;
  • Leave the baby in a raised position, always with support, such as lifting the baby a little or letting him or her pushchair, so that she can better see the world around her;
  • Read books to the baby, always varying the tone of your voice, using accents or singing, as this will help to develop hearing and increase the affective bond;
  • Encourage a baby's touch with different materials such as plush, toilet paper, felt and various fabrics;
  • Touch and massage the baby enough;
  • Always play with the baby, directing him to words and giving time for him to respond with his sounds and gestures;

It is important that the toys given to the baby are large, without tips and without paint so that it is not absorbed by the mouth, and they should also be strong, so that they do not break. In addition, stuffed animals should be avoided at this age as they can trigger allergies.

At this age, the baby should take daily walks, because the more he sees, the more he learns and these should be performed early in the morning and in the late afternoon from 5 pm to avoid crowds.

What should a 3 Month old baby eat

The diet for a baby that is 3 months old should be exclusive breast milk and should be kept, if possible, up to 6 months.

However, many mothers return to work at this stage, making exclusive breastfeeding impossible. If this happens and the mother has difficulty storing her milk, supplement it with age-specific milk powder as instructed by the pediatrician.

How to avoid accidents at this stage

To prevent accidents with a baby from 0 to 3 months, you should adopt certain safety measures. Some of these measures that can help avoid accidents are:

  • Carry the baby always in a proper chair while going somewhere by car, never on the lap and should be facing backward;
  • Do not place the baby in the driver's seat if the airbag is active because it could hurt the baby in the event of an accident or otherwise deactivate the airbag;
  • Do not leave the baby alone on a table or sofa for a second because the baby may fall;
  • Put the baby to sleep belly up to avoid suffocation and Sudden Death Syndrome;
  • Do not put yarn or laces around the baby's neck or hang the pacifier;
  • Do not put objects in the baby's bed;
  • The mattress must be adapted to the bed so that there is no slack and the baby can get stuck;
  • Always check the bath water and milk temperature before feeding the bottle.

In addition, when walking with the baby in a stroller you should apply sunscreen, because even in the shade their skin is very sensitive. They should also wear a hat and clothes that cover the whole body. At this age, it is not recommended you take the baby to the beach.

These measures must be respected by parents to keep the baby as safe as possible.
