Motor Skills

At three months old, babies begin to develop motor skills that involve movement and coordination. Some of the key motor skills milestones for a 3-month-old baby include:

  • Raising their head and chest when on their stomach
  • Supporting their upper body with their arms when on their stomach
  • Kicking their legs when on their stomach or back
  • Pushing down on their legs when their feet are placed on a surface
  • Swiping at and grasping toys
  • Watching faces and objects as they move

These motor skills are essential for the baby’s physical development and set the foundation for further motor skill development later on.

Social Skills

During the third month, babies also start to develop important social skills. Some of the social skills milestones that a 3-month-old baby may achieve include:

  • Babbling and imitating sounds
  • Smiling at familiar faces
  • Playing with others and reacting when the playing stops
  • Becoming more expressive with facial expressions and body language

These social skills milestones demonstrate the baby’s increasing awareness of their environment and their ability to interact with others. It’s an exciting time as they begin to show their personality and engage socially.

What Should My 3-Month-Old Baby’s Feeding Schedule Look Like?

Proper feeding is crucial for a baby’s growth and development. At three months old, babies have specific feeding needs and requirements.

Frequency of Feedings

A 3-month-old baby usually eats every two to three hours, amounting to approximately eight to 12 feedings per day. As they grow, their stomach capacity increases, and they can take in more milk or formula at each feeding.

Amount of Milk

During each feeding, a 3-month-old baby typically consumes around 4-6 ounces of breast milk or formula. This amount may vary depending on the baby’s individual needs and appetite.

Signs of Adequate Milk Intake

To ensure that your baby is getting enough milk, there are specific signs you can look for:

  • Alertness, contentment, and activeness throughout the day
  • Steady weight gain
  • Regular wet and soiled diapers (generally five to six wet diapers per day or more)

These signs indicate that your baby is receiving adequate milk intake and is properly nourished.

What Should My 3-Month-Old Baby’s Sleep Schedule Look Like?

Adequate sleep is essential for a baby’s overall well-being and development. Understanding a 3-month-old baby’s sleep schedule can help establish healthy sleep habits.

Total Sleep Time

On average, a 3-month-old baby sleeps for approximately 15 hours per day. This sleep duration is divided into around nine to 10 hours of nighttime sleep and four to five hours of daytime sleep.

Number of Naps

A 3-month-old baby typically takes two to three naps throughout the day. The first nap often occurs two hours after waking up, followed by a mid-afternoon nap. Some babies may require an additional afternoon nap.

Sleepy Cues

To ensure your baby gets enough sleep, it’s crucial to identify their sleepy cues. These cues can include rubbing their eyes, yawning, fussiness, or appearing drowsy. Responding to these cues by creating a peaceful sleep environment can help your baby transition to sleep more easily.

Sleeping Through the Night

Around three months old, some babies may start to sleep for longer stretches at night. However, “sleeping through the night” for an infant typically means sleeping for a five- to six-hour stretch before waking to feed. Not all babies will be able to achieve this milestone, and it is essential to meet their individual needs for nighttime feeding.

What Should My 3-Month-Old Baby’s Daily Schedule Look Like?

Establishing a daily schedule for your 3-month-old can provide structure and predictability, which can be beneficial for both the baby and the caregiver.

Number of Naps

A 3-month-old baby generally requires two to three naps per day. These naps should be spread out throughout the day, allowing for sufficient awake time and rest.

Best Time for First Nap

The first nap of the day should typically occur around two hours after the baby wakes up in the morning. This timing allows for an appropriate balance of awake time and rest.

Bedtime Routine

Introducing a bedtime routine can help signal to your baby that it’s time to relax and prepare for sleep. A 3-month-old baby’s bedtime routine may include activities such as feeding, bath time, story or song time, or a quiet-time activity. Consistency is key in establishing a bedtime routine.

Are There Any Health Concerns That I Need to Watch For?

Monitoring your baby’s health is essential to ensure their well-being. While most 3-month-old babies are healthy, it’s important to be aware of potential health concerns.

Well-Child Visit

At this age, a well-child visit may not be necessary unless your baby is behind on their vaccines. However, regular check-ups with a healthcare professional are still important for monitoring growth and development.

Conditions Requiring Medical Help

Certain conditions may require medical assistance. If your baby experiences diarrhea or vomiting leading to dehydration, increased irritability with fever or rash, persistent skin irritations or rashes, respiratory infections, or a fever over 100.4 degrees Fahrenheit, it is advisable to seek medical help.

Weight Monitoring

While not typically requiring a well-child visit, monitoring your baby’s weight is crucial. Babies grow at different rates, and on average, they gain about 1 ounce per day during the first three months of life. If you have concerns about your baby’s weight, consult with their doctor for appropriate monitoring.

Monitor Your Baby’s Development

Being aware of your baby’s developmental milestones is important in ensuring their progress. If you notice any concerning signs, such as a lack of response to loud noises, inability to notice their own hands, trouble following objects with their eyes, difficulty grasping or holding a toy, or inability to support their head, consult with a healthcare professional.

What Are Some Activities I Can Do With My 3-Month-Old Baby?

Engaging in age-appropriate activities with your 3-month-old baby can promote their development and nurture your bond. Some activity ideas for a 3-month-old baby include:

  • Clapping their hands together gently
  • Stretching their arms wide or overhead
  • Pedaling their legs while lying on their back
  • Having them focus on a toy and moving it back and forth for tracking
  • Shaking a rattle and encouraging them to search for the sound
  • Talking, reading, and singing to your baby
  • Encouraging supervised tummy time
  • Providing colorful toys with different shapes, sizes, and textures

These activities help stimulate your baby’s senses, promote motor skill development, and encourage interaction and engagement.

Safety Tips for Your 3-Month-Old Baby

Providing a safe environment for your baby is crucial as they become more active and alert. Some safety tips to consider include:

Bath Time Safety

Use a slip-resistant tub, keep the water level low (2-3 inches), and ensure the water temperature is between 96-100 degrees Fahrenheit. Always stay within arm’s reach of your baby during bath time.

Safe Sleeping Environment

Ensure your baby’s crib has a firm mattress and avoid placing pillows, bumpers, blankets, or toys in the crib. Put your baby to sleep on their back to reduce the risk of Sudden Infant Death Syndrome (SIDS). Do not leave your baby unattended with a mobile attached to their crib.

Car Safety

Properly install your baby’s car seat and adjust the straps to the appropriate height. Always ensure your baby is securely buckled in before driving.

Fall Prevention

Avoid leaving your baby unattended on surfaces from which they can fall, such as couches, beds, or changing tables. Always keep a close eye on your baby and provide a safe environment.

By following these safety tips, you can create a safe environment for your 3-month-old baby as they explore and grow.

In summary, the third month of your baby’s life is a significant period of growth and development. Pay attention to their milestones, establish healthy feeding and sleep schedules, monitor their health, engage in stimulating activities, and ensure their safety.
