The development of a 3-month-old baby is an important stage that parents should pay close attention to. At this age, babies enter a new phase of rapid growth and begin to show noticeable progress in their physical and sensory abilities. This is why early stimulation plays such a vital role in supporting your baby’s overall development.
At three months old, your baby’s motor skills start to improve significantly. They begin to recognize familiar faces, lift their heads, roll over, and differentiate between colors. Babies at this stage can also stretch and kick their legs more actively. Some of their newborn reflexes, such as the Moro reflex, will begin to disappear. Around this time, your baby’s sleep pattern may also change — they may start sleeping longer stretches of about six to seven hours. This happens because their nervous system becomes more mature, and their stomach can hold more milk. These longer sleep periods not only help your baby grow but also allow moms to enjoy a more restful night’s sleep.
Another major milestone in a baby’s third month is the improvement in communication skills. Your baby’s hearing and vision become more refined, allowing them to recognize their mother’s voice, smile in response, and turn their heads toward sounds. They may also start to enjoy listening to soft music. At this stage, crying is no longer their only form of communication. Your little one begins to express emotions through coos, smiles, and eye contact. Moms are encouraged to talk and interact frequently with their babies, as this helps stimulate communication and strengthens the emotional bond between parent and child.
When it comes to physical growth, it’s important to remember that a baby’s progress should not be judged merely by how chubby or thin they appear. The most accurate indicators of healthy growth are steady increases in height and weight according to the growth chart. Typically, the ideal weight for a 3-month-old baby boy ranges from 5.1 to 7.9 kilograms, while baby girls weigh around 4.6 to 7.4 kilograms. In terms of height, baby boys usually measure between 57.6 and 65.3 centimeters, while baby girls are around 55.8 to 63.8 centimeters. For this reason, parents should regularly monitor their baby’s growth every month.
The age of three months is also the perfect time to support your baby’s development through various forms of stimulation. One enjoyable and effective way is through playtime.
