12_Month_Old_Baby_Milestones_And_Development_-_New_Parents_Guide

Congratulations baby! Welcome to toddlerhood.

Your baby is finally one year old. He understands simple words and instructions now, points at people he knows, and walks pretty well holding on to furniture or even without support. 

As you celebrate his first birthday, reflect on the exciting growth and development your little one has undergone in the last 12 months, and all the fun and laughs you’ve had together.

And guess what? You are bound to experience even more as your little one marks the incredible 12 month old milestones. Read on! 

What You Should Know

  • Take baby to his 12 month old checkup. At this age, baby will also get measles, mumps, rubella, and chickenpox vaccines.
  • Read to your baby every day to help his language development. 
  • Introduce baby to sippy cups and wean him off the pacifier if he takes one. 

The Most Adorable 12 Month Old Milestones

Many parents with 12 month olds may want to know, “What are the milestones for a 1 year old?” 

At 12 months old, your baby will be sitting without support, crawling or walking from place to place, sleeping through the night, and probably transitioning from formula or breast milk to cow’s milk. His weight and height will display a significant growth too. Below is a breakdown of what to expect as baby achieves 1 year old milestones. 

  • Weight And Height 

On average, a 1 year old should weigh about 21.8 pounds for boys and 21.2 pounds for girls. The average height should be about 29.7 inches and 29.2 inches respectively. 

At this age, baby will likely be three times heavier than he was at birth. He will also be 9 to 12 inches taller and his brain will be about half its adult size.

“Is there a growth spurt at 12 months,” you may ask?

Yes, there will likely be a growth spurt at 12 months, after which your little one will start gaining weight much slower that he did a few months ago. Your baby’s activity level is increasing, which means, most of the calories he takes in are used to fuel his active life rather than being stored in the body as fat, hence the slow weight gain. 

  • The Senses

Sight

Baby’s vision is super clear now. He can see further than just across the room. He can also uncover hidden objects easily by simply moving away the item that is hiding them. And if you store his favorite toy at the same place every time, your little one will look for it at that particular spot always. 

Hearing

At one year old, your baby’s hearing has developed pretty good. He listens more attentively when you speak than he used to. He is also able to coordinate listening and looking now, making reading picture books more fun. 

Touch 

Babies at this age love touching objects of different shapes and textures. They still continue to explore things with their mouth too. 

You little one can also do a variety of grips now; he uses his index finger and thumb (pincer grasp), fingers and thumbs (raking grasp) and his entire palm to grip objects. He also knows how to poke and point at items using the index finger. 

Communication 

By one year, your baby’s vocabulary has expanded and you can pick out a few real words from his babbling. If you are wondering, “How many words is a 1 year old supposed to say?” know that at 1 year old, your baby will probably be saying between one and three words. Of course, some of these words will likely not be complete but you will know what your little one means. 

Some parents may go further and ask, “What should baby say at 12 months?”

At 12 months, most babies can say “mama” and “dada” pretty well and already know which parent each of these words refers to. You may also hear words like “uh-oh” or “no” in their babbling speech. Baby at this age will mimic sounds around him too including the words you speak. 

  • Motor Skills

Perhaps you are wondering, “What should a 12 month old be doing?” Here is what your little bundle of joy will be doing as he hits the 12 month old milestones:

  • Sitting without assistance
  • Walking holding on to your hands or furniture
  • Standing for a short time without support 
  • Taking a few steps without support
  • Pulling to stand
  • Banging objects and toys together 
  • May climbs stairs. Baby proof your stairs to keep your little one safe. 
  • Rolling from front to back and vice versa
  • Using a variety of grips to put finger foods in his mouth
  • Imitating basic gestures like waving and shaking hand

12 Month Old Food

What_should_a_12_month_old_be_doing_

At 12 months old, baby formula and breast milk are still an important source of nutrition for your little one. However, at this age, you can begin transitioning from breast milk to cow’s milk. 

Make sure you are giving your baby whole milk because he still needs the extra fat and nutrients he was acquiring from breastfeeding for his growth.  Do not give baby low fat milk or foods until he is at least 2 years old or unless advised by the doctor. 

Baby is also eating 3 meals a day with 1 or 3 snacks between meals. With the increased activity level, he should be drinking some water too. “But how much water should a 12 month old drink,” you may ask? A 12 month should drink about 1 eight-ounce cup of water per day. This will keep him hydrated and fueled up during his activities. 

12 Month Old Sleep

By 12 months, your little one is sleeping more during the night and less during the day, roughly 13 to 14 hours a day. If he is like most children, he is probably already skipping his morning nap and having a longer nap in the afternoon. 

Some parents may want to know, “What time should a 1 year old go to bed?” 

A 1 year old should go to bed anywhere between 6:30 p.m. and 7:30 p.m. Make sure you are keeping the routine consistent to help baby sleep better through the night

A Day In A 12 Month Old Life

A number of transformations will be observed as baby reaches the 12 month old milestones, more specifically in mobility. If he was crawling last month, he is probably starting to walk, so technically, this is the time to invest on baby shoes. Make sure you are going for the most comfortable pair.  

Baby is also listening to you more and repeating what you say, so be careful what you say around him. 

Moreover, as baby’s curiosity increases, he will be crawling or walking to places he shouldn’t be or touching stuff he shouldn’t. To ensure your baby’s safety, baby proof your furniture and living room, cabinets and drawers, toilet and bathroom, fireplace, and any other area you think could pose danger to baby.  Also, make sure household cleaners are out of reach and dishes and pots are put away from counter edges. 

At this point you may ask, “How do you discipline a one year old?” Here are some ideas:

  • Introduce a couple simple rules for your baby to follow and be consistent
  • Identify and praise good behavior
  • Observe and learn your child’s personality, habits, and preferences
  • Remove objects that shouldn’t be touched
  • Be proactive in situations that make baby uncomfortable 
  • Try to remain calm when addressing bad behavior. Refrain from yelling no matter how frustrated you may be.
  • Avoid physical punishment especially with very young children. Kids this age do not truly understand the connection between their bad behavior (cause) and the pain of your punishment (effect).
  • Instead of spanking, show your little one the correct way of doing things. 12 month olds still don’t know when they are doing something wrong. 

When Should You Be Concerned?

Each baby will grow at his own pace and will achieve the 1 year old milestones at his own time. However, if your baby shows the following symptoms, it would be best to speak to a pediatrician:

  • Can’t stand even with support
  • Hasn’t started to crawl
  • Doesn’t say a single word
  • Doesn’t point at objects
  • Drags belly or legs while crawling 
  • Doesn’t uncover hidden objects even when he can slightly see them
