As your little one turns one, developmental progress may ease up, yet the achievements reached are significant and impactful.

Explore Your Interest

Congratulations on reaching this significant milestone with your 12-month-old. Encourage independence with simple words, gentle discipline, and motor skill play at this stage. Monitor milestones, maintain a sleep routine, and introduce nutritious foods. 

Prepare for an eventful month as your baby is on the verge of hitting exciting developmental milestones. Whether they’re mastering the art of walking with a bit of wobbling or confidently taking off on two legs, each child has a unique mobility journey. Embrace the variations in their progress and enjoy these moments of exploration!

12-Month-Old Development

Around this age, your baby will likely add about half an inch to their height monthly and gain approximately three ounces weekly. It’s important to note that each baby follows their unique growth pace.

Some may experience a growth spurt around 12 months, while others might witness a gradual slowing down of growth as they transition into toddlerhood. Embrace the individual pace of your child’s development!

12-Month-Old Weight and Height

According to CDC guidelines, your baby’s height and weight may vary, but on average, girls are around 28.3 to 29.7 inches tall and weigh 18.1 to 21.4 pounds. On the other hand, boys tend to be a bit larger, with heights ranging from 29.1 to 30.5 inches and weights between 19.6 to 22.8 pounds. 

Keep in mind that these numbers are just typical averages. It’s perfectly normal if your 1-year-old is either larger or smaller. Every child has a  unique pace of growth and development.

12-Month-Old Safety

Your little one is standing tall now, expanding their world and encountering new risks. Ensure your toddling baby’s safety by taking these crucial additional precautions.

  • Place smoke and carbon monoxide detectors throughout your home for safety. Remember to check and change batteries regularly.

  • Use outlet covers to prevent tiny fingers or toys from entering. 

  • Keep electrical cords hidden.

  • Install gates, especially for stairs, to keep your little one safe. They can also be handy for closing off rooms like the kitchen or laundry area.

  • Ensure stability by anchoring furniture like bookshelves and cabinets to the wall.

  • If you have slippery floors, consider carpeting them and ensure your child doesn’t walk or run on them in socks.

  • Regularly check for small items on the floor that could pose a choking risk.

  • Keep batteries and battery-powered items out of reach. Safely dispose of old batteries and secure battery compartments to avoid accidents.

12-Month-Old Feeding

As your baby turns one, breastfeeding can continue for up to two years. Some moms choose to start weaning around the one-year.

While your little one’s body is ready to handle a variety of foods, keep in mind that their teeth are still coming in, so some tougher foods may be challenging to chew.

Introduce cow’s milk after their first birthday, even if they initially resist the taste. Choose Vitamin D whole milk for the essential fats your child needs.

Be cautious not to overdo it with milk, as you want them to focus on calories from food. Offer milk during meals, limiting it to breakfast, lunch, and dinner. Ensure your 12-month-old gets three meals and at least two snacks daily, and encourage water intake while avoiding sugary juices.

Feeding Habits

Now that your baby is 12 months old, aim for three meals a day and consider incorporating two healthy weaning snacks in between. Opt for nutritious options like fruits, vegetable sticks, toast, bread, or plain yoghurt.

Keep in mind that it’s unnecessary to add salt or sugar to their food or cooking water. Avoid salty foods as they aren’t beneficial for their kidneys, and be mindful of sugar intake to prevent tooth decay.

Breastmilk still provides important nutrition and protection against disease at this age, but other foods become your child’s main source of nutrition and energy. Feed your baby other foods first and then breastfeed after if they are still hungry.

What to Feed Your 12-Month-Old

Your baby can now enjoy a variety of foods, so make each meal nutritious by including foods from your family’s menu. Ensure they have portions of animal foods, legumes (like chickpeas or lentils), nuts, orange, green vegetables and fruits daily. Incorporate a bit of oil or fat for added energy.

Regarding snacks, choose healthy choices like fresh fruit to keep their diet balanced and wholesome.

12-Month-Old Sleep Pattern and Tips

As your little one reaches 12 months, their sleep needs undergo a shift. According to the American Academy of Sleep Medicine, moving from 12-16 hours to 11-14 hours of sleep, this transition is gradual and unique to each child.

While it may have already begun or is on the horizon, aim for a consistent 10-11 hours of uninterrupted nighttime sleep. Complement this with two daytime naps to support their evolving sleep patterns and ensure they get the rest they need.

Sleep Regression

As your baby reaches their first birthday, the growth and development they’ve undergone can be truly astonishing for you. Many 12-month-olds exhibit increased size, activity, and responsiveness, often settling into a more consistent sleep schedule.

However, it’s essential to recognize that sleep patterns for children at this age can still change.

Even if your child has begun sleeping through the night, it’s not uncommon for them to face challenges, such as struggling to fall asleep or waking up frequently during the night. These episodes are commonly referred to as sleep regressions, and they can manifest at various points in a baby’s development, with the 12-month mark being a common occurrence.

Separation Anxiety

Babies are remarkably adaptable to different caregivers, often causing more anxiety for parents than the infants themselves. Most babies under six months easily adjust to others if their needs are met.

Between 4-7 months, infants develop “object permanence,” realizing that people exist even when out of sight. However, they lack a sense of time, making them uncertain about a caregiver’s return. This period can lead to distress when separated, regardless of the caregiver’s location.

As your baby grows to be more independent, from 8 months to 1 year, separation anxiety intensifies. This stage may trigger agitation, crying, and resistance to attention from others when you leave, even briefly.

To help ease separation anxiety, try establishing a consistent goodbye routine, provide comfort objects like a favorite toy or blanket, and reassure your baby with soothing words and gestures.

Sleep Tips for Your 12-Month-Old

  • Establish a calming bedtime routine to signal that it’s time to wind down. This might include activities like reading a book, a warm bath, or gentle rocking.

  • Ensure the sleep space is conducive to rest – dim the lights, maintain a comfortable temperature, and use a cozy blanket.

  • Around 12 months, some children transition from two naps to one. Monitor your baby’s cues and adjust the nap schedule accordingly.

  • Help your baby learn to fall asleep independently by placing them in the crib when drowsy but still awake. This helps them learn to comfort themselves and settle into sleep independently.

  • Strike a balance between naps and wakefulness during the day to avoid overtiredness, which can disrupt nighttime sleep.

  • Introduce a comfort item, like a soft toy or blanket, to provide reassurance during the night.

  • Limit exposure to screens, including TVs and tablets, close to bedtime, as the blue light emitted can interfere with the natural sleep-wake cycle.

Remember, each child is unique, so finding what works best for your little one may take trial and error. Consistency and patience are key as you navigate your 12-month-old’s sleep routine.

12-Month-Old Senses

As your baby hits the one-year mark, their senses are nearly fully developed. Their vision is sharp, comparable to most adults, and they’re becoming good at recognizing people, places, and objects. 

Your child’s vision has been developing over several months, and now they can see clearly both near and far, even tracking swiftly moving objects. The coordination between their motor skills and eyesight is improving, allowing them to spot a toy across the room, focus on it, move toward it, pick it up, and explore it in various ways.

While familiar faces remain their favorites, your baby might also show interest in looking at pictures in books, especially those with familiar images. Objects with moving parts can captivate their attention, leading them to spend considerable time examining and manipulating them to understand how they work. To enhance their experiences, take your baby to new and intriguing places, pointing out and naming different sights along the way.

Now that your one-year-old’s hearing is fully developed, they’re getting the hang of individual sounds and words, recognizing that people, places, and objects have names. Your child may begin linking names to specific objects, responding to cues like their name or finding requested items. Interact with them through simple commands or questions to see how much they grasp.

With their well-developed hearing, create joyful moments by turning up the music and watching your little one dance to the beat. Keep reading and singing; these shared experiences play a vital role in shaping their imagination for the future.

As your baby becomes more independent, mastering the art of scooting, crawling, or walking, they’re eager to explore the world around them. Ensure the environment is safe, removing potential hazards, and let your baby touch and experience various textures and surfaces at home and in the yard.

Encourage sensory exploration—let them feel the mushiness of a banana on the highchair tray, the hardness and coldness of ice cubes, or the contrasting textures of sandpaper and a stainless-steel sink. While these discoveries unfold, your loving touch remains paramount; seize every opportunity to give hugs and kisses, reinforcing the connection between you and your little one.

As your 12-month-old explores new foods, their sense of taste is still evolving. You might observe preferences emerging, with some foods more appealing than others. Keep introducing a range of tastes and smells, and be persistent if they don’t take to a particular food immediately—it may take ten tries or more for them to develop a liking.

How to Recognize Signs of Discomfort in Your 12-Month-Old

  • Watch for deviations from your baby’s typical behavior, including reduced appetite, fussiness, or restlessness.

  • If your baby experiences crying that cannot be comforted, it may indicate discomfort or distress.

  • Pay attention to unusual vocalizations like grunting or breath-holding during moments of discomfort.

  • Look for changes in facial expressions, such as a furrowed brow, wrinkled forehead, closed eyes, or signs of anger, providing insights into your baby’s emotional state.

  • Disruptions in sleep patterns, including frequent waking or altered duration, can indicate discomfort. Even severe pain might lead to shorter naps due to exhaustion.

  • Observe body movements such as making fists, protective gestures (especially while walking), kicking, clinging to caregivers, or reduced mobility, which can convey discomfort or pain.

Monitoring these cues can help you respond promptly to your child’s needs, ensuring their well-being and comfort. If concerns persist, consult with a healthcare professional for guidance and support.
