Baby Milestones Chart: A Week-by-Week Guide to Development

Baby Milestones Chart

So you are a new parent, pregnancy is over, and your baby has entered the world. You may be thinking about baby growth, and for a good reason. Baby milestones are a great way to see if your baby is growing and developing, so they should leave you with nothing to worry about regarding their health.

In this guide, we will be giving you an idea of the kind of milestones your baby should have reached by certain weeks in the early stages of their lives. All these resources are there as a guide, and it is important to know that babies develop at their own pace. Some will pick up certain things before others, and you shouldn't worry if your baby isn't completing every achievement by a certain week.

What is a baby milestone?

A baby milestone is a checkpoint in growth, such as a baby's first smile or a baby's first word. These achievements help to see if your child is healthy in both a physical and mental way.

Support can be given to nurturing your child's growth after pregnancy, but a baby may reach some areas faster than others all on their own. The majority are just a rough indication and can allow you to know your baby's health and fitness.

Why are milestones important for babies?

Baby milestones are important as they offer strong indications of the developmental health of your child. Expected achievements show the typical growth that is to be expected from children at a certain period of their life.

Reaching a milestone early could indicate advanced levels of intelligence compared to other children -but remember, babies develop at their own pace, so you shouldn't try to force them to do things they simply cannot.

Baby milestones by week

Newborn Milestones

There are many baby's first steps with newborns, they have just entered the world, and everything is new. Many changes surround them compared to their life during pregnancy, and now they have taken their first steps in becoming a person.

Here are a few newborn milestones you may notice:

  • Enjoy looking at faces
  • Enjoy looking at different coloured toys

8-Week Milestones

The 2-month baby milestone is a crucial one, and you should take close notice of what your baby is achieving at this point.

The 8-week baby milestone should be as follows:

  • Your baby will begin to smile at people.
  • Begin to calm themselves down, such as raising a hand to the face in a soothing manner.
  • Begin to recognise people at a distance and follow things with eyes

  • Leg and arm movements are smoother
  • Start to push when lay on stomach

  • Hold their head steady and unsupported
  • Begin to push onto elbows when lay on the stomach.

  • Begins to pass toys and other things from one hand to another
  • Can sit unaided
  • Begin to understand simple words
  • Will respond to their own name

By 28 weeks, your baby will begin to:

  • Seek pleasure dropping things on the floor
  • Play games such as peek-a-boo
  • Respond to the word no
  • Can find slightly hidden objects

By week 32, your baby milestones will be:

  • Development of the pincer grasp using the index finger and thumb
  • Start to crawl
  • Can hold things while standing

36-Week Milestones

Your baby will start playing around with a range of tones and sounds by week 36 and is getting ever so closer to the all-important milestone of talking. If you're not hearing the first mama or dada yet, don't fear - children start talking at different times.

Although they should be making progression, speech isn't always one of the early tools babies pick up. By 36-weeks your baby should be:

  • Becoming wary of strangers and very clingy to people they recognise
  • Has a favourite toy
  • Will start to make a range of sounds
  • Begins to copy gestures and sounds of others

A 10-month baby brain cannot be rushed or fast-tracked in its development, so you should never try and force them to do things they simply aren't working towards yet.

The 10-month baby milestones are usually:

  • Begin to crawl upstairs under supervision
  • Make different tones with their voice sounding more like speech
  • Has more object understanding
  • Begin to become attached to parents with more separation anxiety shown.

  • Say "mama", "dada", or other interjections such as "uh-oh".

  • May stand unaided.
  • Begin to take steps with being held.

52-Week Milestones

While there are still many more things for your baby to learn, they are well on their way to becoming an independent infant. By 52 weeks, your baby will start to actively dream in their sleep. These dreams can even startle or scare your baby, and you should do your best in comforting them until they fall back to sleep.

Language skills begin to develop, and walking is becoming more stable. Your baby's self-awareness is also beginning to develop, giving them more assurance in themselves and more confidence to play with other toddlers and interact with strangers.

By 52 weeks, your baby should:

  • Begin to walk unaided with less of a wobble
  • Enjoy interacting with other toddlers
  • Start to dream
  • Language skills develop


What are the normal developmental milestones for babies?

Crawling, walking, rolling over, and talking are all considered baby milestones. There are different ones for different ages with a normal range that most children will usually reach around the same time.

All babies will develop and grow at their own pace, with some children walking as early as eight months, whereas this is usually around ten months later.

How do you know if your child is advanced?

If you feel that your child is advanced, there are a few key signs that you can try to be aware of, which you can then nurture to help your baby's development further. Some key ways to know if your baby is advanced is if:

  1. Your baby is hitting milestones that similar-aged babies are not yet.
  2. Has great focus.
  3. Enjoys problem-solving.
  4. Prefers time on their own.
  5. Weighed a lot at birth.
  6. Has a lot of curiosity.
  7. Has high alertness.

When should I worry about baby milestones?

You may need to start to worry about a few milestones if your baby is not reaching them by a certain age. Baby milestones are usually around the same time.

Although all babies will develop at their own pace with some late walkers and late talkers, a few checkpoints are usually reached by a certain age.

If your baby isn't reaching these milestones, you may want to visit your GP or health visitor:

  • If your baby can't track things with their eyes or respond to noises.
  • Doesn't show curiosity about things around them.
  • If your baby isn't holding their head up by 3-4 months.
  • If your baby isn't sitting up unaided by ten months.
  • If they don't use their own arms and legs, or by 12 months, they can't support their own weight.
  • They seem behind other babies of a similar age by a long way.

This won't be a problem most of the time, but it is always better to be safe to check if you feel any of these areas are an issue. It is also worth mentioning that if your baby had a premature birth, they would usually reach their baby milestones as if they were born after nine months.

What milestones should a 3-month baby be doing?

Some of your child's most critical growth and development begin in the first three months, with many baby milestones being reached. Infants will start to understand their body movements and learn how to interact with others.

There are a few key baby milestones that your baby should reach by three months, these are:

  • Can push up on arms while lying on tummy.
  • Can lift and hold head up while lying on tummy.
  • Able to move fists from closed to open.
  • Able to move hands towards the mouth.
  • Can move hands and legs on a surface when excited.
