Baby Development By Week: The First Three Months

baby development by week

As new parents, we are often curious about what is happening with our baby on a week-to-week basis. It can be hard to know how their development compares to other babies of the same age, and it’s easy for us to focus more on the negative things than the positive! But as they say: “what doesn’t kill you makes you stronger.” So let’s take a look at some of those developmental milestones that come in those first three months …

Baby Development By Week: The First Three Months

0-week old baby: 

This tiny little being is just starting to form and will continue growing and developing in the weeks to come. Although they are not able to do much at this stage, they are already taking in information from their environment!

One-week old baby

Babies at this age are typically very alert and will start to focus on faces and objects that are around them. They may also start to make some noises, such as cooing and gurgling.

Two-week old baby

Babies at this age typically continue to be very alert, and will now gradually start to track moving objects with their eyes. They may also start responding more to voices, and may even start to smile!

Three-week-old baby

Babies at this age typically continue to be very alert, and will now try to reach for objects that they see. Additionally, they may start sucking on their fingers or thumbs, or even cry more frequently!

Four-week-old baby

Babies at this age typically become more active and will start moving their arms and legs around. They may also start to recognize people, and may react differently depending on who is talking to them.

Five-week-old baby

Babies at this age typically become even more active and may start to roll over from their back to their stomach. They may also start cooing more, and begin to develop a personality of their own!

Six-week old baby

Babies at this age typically continue becoming more active and may start to push themselves up on their hands and legs. They will begin making more different types of sounds, including “cooing” and squealing!

Seven-week old baby

Babies at this age typically start to become more independent and will spend more time playing by themselves. They may also start to develop stranger anxiety, and may react negatively when someone they don’t know tries to touch them. Their ears are also fully developed, and they will now begin to recognize your voice!

Eight-week old baby

Babies at this age typically start to become more independent and will try to roll over on their own. They may also start sitting up with support, and may even try to grasp objects!

Nine-week old baby

Babies at this age typically start to become a little calmer and will spend less time squirming around. They may start sucking on a pacifier or their thumb and will begin to develop attachments to certain people or items.

Ten-week old baby

Babies at this age typically become more calm and relaxed, and will now be able to focus on certain objects. They may start cooing or even “talking”, and can grasp small items with their hands!

Eleven-week old baby

Babies at this age typically continue developing a stronger personality, and will now be able to focus on objects even better. They may start making sounds, or begin smiling at certain people!

Twelve-week old baby

Babies at this age typically continue becoming more independent and can sit up with less support from others. They may also try reaching for things that are in front of them, and will start to imitate some sounds that they hear!

So as you can see, even in these first three months your baby is constantly developing and changing – sometimes in small ways, and sometimes in very noticeable ways. 

Just because they can’t walk or talk doesn’t mean they’re not learning and growing! And by keeping a close eye on your child, you’ll be able to better track their progress and notice any changes that they might need help with.

You may also want to buy some developmentally appropriate toys and newborn baby toy-set during this period. 

What Can You Do To Promote Baby Development By Week?

Now that you have a general idea of what to expect developmentally during the first three months, let’s talk about ways that you can help promote your child’s growth. 

There are seven steps that you can take to help support your baby’s development and for excellent parental bonding during these early months: 

Make Sure Baby Gets Plenty of Stimulation 

One of the best things that you can do for your child during their first three months is to make sure they get plenty of stimulation. This means exposing them to new sights, sounds, textures, and smells. It also means interacting with them frequently – talking to them, singing to them, playing with them. 

Nurse or Bottle Feed on Cue 

Nursing or bottle-feeding on cue will help ensure that your baby gets the nutrition they need and helps to promote healthy digestion. It also helps to form a strong attachment between you and your child. 

Respond Quickly to Baby’s Cues 

When your baby cries, fusses, or makes other noises, it’s important to respond quickly. This helps them to feel safe and secure and teaches them that they can rely on you to meet their needs. 

Encourage Baby to Self Soothe and Sleep Through the Night 

When babies sleep through the night, they feel rested which helps them develop physically and emotionally. They also tend to be happier during their waking hours because they don’t experience as much stress from being tired. Babies are more likely to sleep well when they’re in a familiar environment and when you respond to their cues. 

Make Sure Your Baby Is Covered by Health Insurance 

Getting your child’s health insurance as soon as possible is very important because it allows them to receive the medical care that they need if something goes wrong. It also ensures that all of their doctor’s visits are covered. 

Take Baby to the Doctor for Well-Baby Checkups 

The well-baby checkups are a great opportunity for your child’s doctor to assess their development and make sure that they’re on track. They will also be able to give you advice on how to promote your child’s development at home. 

Schedule Baby’s Immunizations as Directed by the Doctor 

The doctor will let you know when your child needs to have their immunizations, which include vaccines against polio, measles/mumps/rubella (MMR), diphtheria/pertussis/tetanus (DPT), varicella (chickenpox), and hepatitis B.

 By following these steps, you can help your child develop healthy habits that will benefit them for the rest of their lives. You may also want to talk to your doctor about other ways in which you can promote development during this time period such as enrolling in a local playgroup or signing up for infant massage classes.

Final Words

We hope that this gives you a little snapshot of what to expect from your baby during the first three months of their life. Every baby is different, so don’t worry if yours doesn’t follow this exactly – every milestone is something to be celebrated! And as always, if you have any questions or concerns, please talk to your doctor.
