When Do Babies Learn How To Open Doors?

Picture this: your curious, energetic toddler suddenly goes silent. As a parent, you know this can’t mean anything good. You race to the scene only to discover your little one standing triumphantly on the other side of a previously closed door. Shocked? Perhaps. But every parent experiences this moment—the moment when their toddler masters the art of opening doors. Typically, toddlers begin to open doors around the age of two years, although some precocious 16-month olds may surprise you.But is this just a random act, or is it a developmental milestone worth considering? Let’s dive in and find out!

The Importance of a Baby’s Motor Skill Development

The day when a child manages to open a door marks a significant leap in their motor skill development. This isn’t just about them being able to get into rooms they previously couldn’t—it’s a reflection of their growth, a testament to their cognitive and motor skills advancement. For toddlers, opening a door is like solving a puzzle or cracking a code. It’s about identifying the door handle as a tool and learning how to use it to achieve a desired action. And trust us, once they crack this code, there’s no turning back!

Understanding the process of a baby developing these skills can be a fascinating journey. At around 15 months, babies begin to show interest in manipulating objects. They might pick up their teddy bear with more control or start using tongs to squish play dough. By 16 months, they can stack blocks, and by 24 months, they can unscrew jars—a small but significant victory for their little fingers!

Consider how exciting this phase is for them. Every new object is an opportunity to learn, a chance to measure their growing capabilities. When they first try to open a door, they’re not just exploring—they’re pushing their boundaries. Watching your child grow and develop these skills can be like watching the world around them open up, one door at a time.

Observing Your Toddler’s Progress

At around 16 months, your child is most likely at the stage where they are beginning to reach for door handles. This shows they have developed a level of object recognition and have associated doors with the concept of opening. They are now observant enough to copy actions they see, including turning a doorknob. But don’t be too concerned if they aren’t there yet—developmental milestones can vary greatly from child to child.

As toddlers become more mobile and inquisitive, it’s essential to be observant and provide safe spaces for them to explore. It’s during this time that you might notice your little one attempting to open doors. It might start with them trying to reach for the handle and might be followed by a few unsuccessful attempts to turn it. But with time, and perhaps a bit of help, they will master the action.

The Role of Toys and Play in Skill Development

Playtime is critical for children’s development, and toys play a substantial role in this. At around 16 months, your toddler might be able to stack cups or arrange blocks. Playing with these toys encourages them to engage their fine motor skills, which are the same skills they’ll use to eventually turn a doorknob.

Consider providing your child with toys that challenge them and help develop their motor skills, like puzzles or toys with buttons and switches. Some toys even mimic real-world objects, like play kitchens with cupboards and doors. Playing with these toys can help them understand how certain objects work, including doors.

Preschool Age and Door Opening

By the time your child is ready for preschool, they should have mastered the skill of opening doors. Most children are adept door openers by the age of 2.5 years. However, if your child hasn’t mastered this skill by preschool age, don’t be too concerned. Each child progresses at their own pace, and what’s normal for one might not be the same for another.

Preschool is a time of rapid growth and learning, where children continually explore their world. They become more coordinated and can complete tasks like putting on their shoes and, yes, opening doors. This skill signifies a level of independence that will only continue to grow as they step into the world of kindergarten and beyond.

Baby Proofing for Your Little Explorer

As your child masters door opening, it’s essential to keep their safety in mind. After all, their newfound ability can lead them to areas of your home that may not be child-proof. Secure rooms that pose potential harm, like the kitchen or bathroom, with child safety locks on the doors.

Keep in mind that just as toddlers are good at learning, they are equally good at problem-solving. Some children might be able to bypass child safety locks before you know it. Stay a step ahead by ensuring harmful objects are out of their reach and continually reassessing your home’s safety as your child grows.


In conclusion, the art of door opening, while simple for adults, is a significant milestone in a toddler’s life. It signifies their ability to interact with the world around them, demonstrating their motor skills and cognitive development. While it may raise safety concerns for parents, it’s also a proud moment that deserves celebration. Remember, each child is unique and will achieve these milestones at their own pace. As Shelov (2004) notes in his study on toddler development, the key is to observe, support, and provide a safe environment for exploration.
