5-month-old baby developments:

Before we start talking about the developments of a 5-month-old baby, we should mention that all babies are unique and meet these developments at their own pace. This article merely shows what your baby has the potential to accomplish and how you can help him/her do it better.

Visionbaby sees tiny objects

5-month-old baby can spot and follow smaller objects that move around him. If you show him part of his favorite toy, you will see he recognize it and want to have it which means he recognizes things by seeing part of it. This also shows that they start to realize when something is not within their sight it still exist. They are getting better at understanding the difference between two shades of the same color. But still they prefer their old color friends, the brighprimary colors.


It takes time for your baby to learn how language works so she will continue to watch intently your mouth and listen to your voice as you talk. She might react to her name when you call her (she is so smart, isn’t she?). She will make many sounds, and this is her attempt to imitate the sounds she hears from her environment.

Muscles and Motor skillBaby Sitting

He can SIT now, with a little help. But still it counts as sitting right?

You may need to make her a CushionLand because she can fall time to time. They are pretty awesome with their hands. They have both hands synchronized with their eyes. They reach for a toy, grab it, pass between hands and then inspect it carefully (yes it means examining in their mouth).

Crawling is on the horizon! After he masters his rolling from back to front and vice versa, then he might start crawling. Crawling is actually a crucial skill for him to discover the world around him and it’s a major step for your baby to be able to walk someday.

Communication skill

Your baby is becoming much better at communicating with you. She will continue to make new sounds to get you attention and express their needs. This way she can practice her language skills. When she finds a new sound, she will repeat it many times to make sure she has learned it. She may also laugh at silly faces and funny noises you make.

She starts using her hands to show you her feelings. She will give you hugs and ask you to pick her up by holding her arms up (heart melting moment). You can now get a reaction from her when you call her name (pretty exciting, right?).

 Social skill

For babies at this age, it’s normal to see some sort of stranger anxiety. He will make it clear that he is comfortable around people he knows. If you didn’t isolate yourself for the last couple of months from you family and friends then it’s less likely that he dramatically reacts to strangers’ presence.

Cognitive skillbaby-Cognitive skills

Babies can understand they can change in their surroundings, but they can’t remember it. Recalling the actions-reactions phenomena might happen at this age, and that’s why your baby will repeat her action to see the same reaction from her surroundings. Not all of these repetitions or experiments are fun, for example, she may cry for no reason, waits for a second to see if anyone would come or not.

She may now understand that if she doesn’t see an object (a toy) that object still exists (object permanence).

Other development:

TeethingBaby Teething

A full set of primary teeth will take 2.5 to 3 years to get complete. Between ages of 4 to 7 months, Lower central incisors will appear. When your baby’s first tooth shows up, you might be taken by surprise especially when they grab your finger and bite it!

Teething may come with fever and diarrhea. Diarrhea happens because he will drool crazy before and during teething. For fever, it’s always good to check it with your doctor.


Besides tasting, touching is you baby’s most important sense to detect and explore her world. She likes to be touched and get the massage and feel your warmth. She also loves to give you a hug.


 If you think your baby wants to eat what you eat (look at his reactions during lunch or dinner) then make sure when you place something in his mouth he doesn’t push back hard with his tongue. He should be able to control his head and be able to chew and swallow. As we mentioned before up to age six months, your baby will get all nutrition he needs from your milk. So don’t rush and get advice from your pediatrician.

Sleeping:Baby Sleep

By five months old you may find your baby is sleeping through the night (6-7 hours). During the day, your child will need two nap times (in the morning and after lunch).



How to help your child develop at this age


As we mentioned, your baby is discovering that objects exist even though she cannot see it, which is why she loves to play peekaboo (at the bottom of this page)

A mirror can be a great toy for her because as she moves the reflection in the mirror moves. It is fascinating for her even though she doesn’t know that’s her own reflection.

A crib mobile still is an excellent product to stimulate her vision, especially with brighand colorful hanging toys.

HearingBaby Listen to Music

5-month-old baby will clap his hands, smile and babble along with a song. He might like jazz or pop or classic. Children love music.

As we said, they like to hear new sounds so give him a set of keys (plastic ones) or install a wind chimes somewhere.

You can call his name very softly from behind and see if he can hear you and turn back.

Muscles and Motor skill

Your baby needs some help to sit for a short time. You can open her leg to make a “V” shape. This way it’s easier for her to balance herself. Don’t forget to make the cushion-land.

Still she needs Tummy-time to strengthen the muscles she needs to sit up and walk someday. Put a colorful toy in front of her to make her moves toward it by crawling.

Place a toy in one of your baby’s hands and then another. They will soon learn to pass the toy from one hand to the other all by themselves

When you pick her up, she will start kicking in the air. This is a good exercise for her leg.

Communication skillbaby Laughing

When your little one makes noises, try to repeat it with her. This will encourage her to do it again and again, which will help her to learn to talk.

 Make funny faces with different voices and sounds. Try to be a kid again.

Name her toys and as you give them to her repeat their names, to help teach your baby new words.

Social skill

It will be the best if you take him out for a walk or shopping. It’s a new and exciting place for your baby.all the people around making noises. Just make it short so it won’t become overstimulating for him.

By doing this, you will expose him to people, situations, and places.  This builds baby’s confidence and helps him to feel more calm and comfortable in the presence of strangers.

Cognitive skill

Peek-a-boo! Put a toy under a blanket, and then whip off the blanket for the big reveal. It’s an excellent way for your baby to learn that things that disappear can magically reappear. There are also some peek-a-boo books that are very well made.

Other development:


As we mentioned it before for 4-month-old developments, One of the best ways to calm your baby is using your clean finger and rubs it on his sore gums. But this can’t be done all the time, you need more practical methods. Giving your little one’s cold washcloths or teething toys is one of the most effective ways to reduce the pain.

If these methods aren’t working, some doctors recommend giving a teething baby children’s pain reliever such as infants’ acetaminophen. Always ask your baby’s doctor for the correct dosage before giving acetaminophen to a child younger than two years old.


You can still use the same things you did for a four-month-old baby. So try to talk about different part of her body while you touch them. Singing or talking to her, stimulate not only her brain but also enhance your loving relationship. Regular massaging your baby will help her to recognize different parts of her body.

You can stimulate her sense of touch using different textures like fur, wood, glass, tissue, felt, velvet and towel. You can check for board books that introduce different texture and make touching a part of the reading experience.


If you established a nighttime routine, then try to follow it every night. You can feed him, give him a bath, put him in pajamas, sing him a song and sway him, put him down in his crib, read a book with a soft voice and play some music (music box or crib mobiles). This routine gives your little one time to calm down and feel sleepy during the process.


If you discussed the solid food with your pediatrician, then remember it will be a new experiment. Your baby is not 100% sure, so she might not eat more than a tablespoon.

Oatmeal cereals are the least of the allergenic grains; you try this first for your baby. Anyway its texture has to be smooth


  • She can roll over, never leave her on the high surface alone.
  • Baby-proof your house (crawling is coming)
  • The American Dental Association suggests that you take your baby after the first tooth to a dentist and no later than the first birthday.  So if your five-month-old has his first teeth, it’s the right time to see a pediatric dentist.

We hope you find this review informative and helpful. Now it’s easier to find appropriate toys and gears for kids. Please let us know if you have any question. We will try to answer it as soon as possible.
