Baby Milestones From 12 – 15 Months : Week-By-Week Guide


Medically Reviewed By

If you’ve been wondering what to expect in your baby’s first year, you’ve come to the right place. Here are the key milestones for this critical age. At this age, your baby will begin to sit unaided and pull up to a standing position. In time, your child may start crawling, leading to walking. By 12 months, your child can feed themselves finger foods, grasp objects between his thumb and forefinger, and play with toys.

During this period, your baby will start to understand emotions and socialize. They will be more likely to express their feelings and start using gestures and emotions to communicate them. They will also begin to understand how to share with other people and may even display signs of embarrassment when others watch them. These developmental baby milestones are key ones for parents to watch for and monitor.

Baby milestones month by month guide

Week 53

Your baby should be showing more signs of socialization and may start smiling more often. This is not yet a sign that your baby is ready to be fully independent. A baby’s clinginess may be a sign of insecurity. However, this week is a great time to reassure your baby and help them feel comfortable. During this time, it’s important to remember that your baby’s body is still developing and susceptible to illness or pain.

Week 54

Your baby will begin to develop opinions and emotional awareness. Your baby will be able to recognize the presence of things and will begin to make decisions about the world around them. They will also learn to regulate their environment. This is an important milestone as they begin to learn how much they can handle. Following a schedule can help your baby develop a sense of security and independence.

Week 55

At this point, your baby will start distinguishing objects by sound and colour and will begin categorizing things. They are learning how to use their thumb and forefinger to grasp objects and play games with them. During mealtimes, they may grab a spoon or play with a container and turn it over. This is a great way to reinforce the idea of object permanence.

Week 56

A new toy can be an excellent way for your baby to develop language and hand-eye coordination. Make sure the toy is big enough to prevent choking. A wooden spoon and an upended ice cream container make wonderful drums. These toys help your baby develop sensory skills and cause & effect. It is also fun for parents to see their babies learn to make fun faces by holding and putting things into their mouths. Your baby may also imitate the sounds you make, like clapping.

Week 57

During this wonderful week, your baby is likely to be clingier and more irritable, which can be a sign of insecurity. Although this phase is short-lived, don’t worry. By being as close as possible to them, you can help them feel better and encourage them to grow up! During this stage, they will also begin to grasp and understand the meaning of words. It is also important to remember that your baby is learning the language.

Week 58

This week, your baby is developing a strong sense of smell and is learning to recognize patterns in the world around them. They may start to sit or roll up. And as their body starts to get bigger, your baby’s movements become smoother. As they grow, they will also recognize patterns in the world around them, such as familiar things and objects. Your baby may also start to notice familiar objects around them, which can help you bond with them.

Week 59

You may want to consider starting baby-proofing your home at this stage. This is because babies are inquisitive and mobile at this age, and they will leave a trail wherever they go. You may find that your baby is stealing books from shelves, clearing cabinets of their contents, and even tipping over wastebaskets. These activities are all part of a baby’s natural curiosity. 

Week 60

At this age, your baby has started to notice patterns and is learning to orchestrate events. You might have noticed that your toddler has started to play with a ball or roll it back and forth with you. They might also have begun to drink from a cup, though they may still prefer a bottle. They are also standing up and walking unassisted and are getting increasingly independent.

Week 61

By the time your baby is 61 weeks old, they are learning to group objects together and make goals. Using these goals as inspiration for fun activities, your baby will be able to recognize the steps involved in doing the things they enjoy. If you can, try introducing a new food as a treat. 

Week 62

Week 62 of your baby’s development includes a variety of new milestones of baby, from sitting to crawling. An increasing level of independence characterizes this developmental stage. During this time, your baby may also learn to hold and manipulate objects with their hands. You can reinforce this development by hiding a toy under a cup or blanket.

Week 63

Aside from recognizing the familiar sounds and sights of objects, your baby will also recognize the objects that are out of sight. They will look under blankets to find misplaced books and turn containers upside down to discover toys. In week 63, your baby will begin to connect sounds and colours with objects. A rattle will trigger an expected response, and your baby will prefer to explore objects with bright colours and three-dimensional features around the house.

Week 64

Your baby may be too excited to sleep during this week. Try to develop a regular bedtime routine that signals it’s time to sleep. Try singing to your baby as you hold them in a darkened room. Your baby will be more likely to fall asleep if you can provide a relaxing bedtime ritual. The baby is learning how much they can handle and will enjoy a soothing ritual. By week 64, your baby will be able to do more than just crawl around the house.
