Child Proofing Doors: Knobs, Locks & Other Solutions for Restricted Areas!

Childproofing your doors doesn’t have to be so hard.

We’re not saying it’s fun or that you want to be doing this on your day off, but our guide below should make it a tad easier so you’re not curled up in a scared and anxious ball in the childproofing section of the local shop trying to figure out what on earth it is you exactly need to be getting.

Toddler in diapers trying to open door and get out of the house

We’ve covered everything you need to know, from understanding the dangers of keeping doors around the house not baby proof to properly choosing your locks, and even a DIY solution some of you might choose to experiment with and build on.

Ready to dive in? Alright, let’s do this!

Why Do You Need To Babyproof Doors?

No doubt your sanity is at stake (there’s only so many times a day you can listen to the bedroom door slamming shut).

But your child’s safety is really the number one concern.

Here’s why you need to do this task, regardless of the types of doors you might have around the house.

Getting Fingers Caught

How many times have you heard the door slam and your little one comes toddling out, tears streaming, nursing their hand? Hopefully never. But it does happen.

According to the Raising Children Network, the hinge side of the door often causes the worst injuries. This is especially the case for one to two-year-olds. Meanwhile, they say that older children are more likely to hurt themselves in the opening or handle side of the door.

If this happens to your child, this article from the American Academy of Pediatrics offers great information on home treatment and when to seek professional advice.

Going Places They Shouldn’t

Sometimes we keep rooms shut off for a particular reason. Like the garage, or the laundry. With power tools and chemicals, these certainly aren’t ideal places for a child to be alone.

Possible danger zones in and around your home need to be blocked off, which means you have to secure the doors.

Getting Stuck On The Other Side

It’s a mysterious science – our little ones are savvy enough to get into the room, but often just can’t get out.

While it’s annoying for us having to constantly free them, it’s also not fun for your little one, feeling trapped and scared. Even if they will do it again five minutes later …

Escaping Through The Front Or Back Door

This isn’t so much an issue when they’re babies, but small children may eventually work out how to open the lock on the doors that lead out of the house.

The dangers here are pretty obvious – running onto the road, getting lost in the street, talking to strangers, etc. Basically, your child shouldn’t be leaving the house without you knowing, which is why an additional childproof doorknob lock may be necessary.

When Should You Babyproof Your Doors?

It makes sense to babyproof your doors by the time your little one is walking and able to use the knob or handle. This could occur any time from about nine months onwards, depending on the height of your door handles and your baby’s development.

But to be honest, injuries can occur even before your little one can reach the handle.

Babies that are crawling and pulling themselves up onto things can easily push doors ajar by accident. Or, as we mentioned earlier, get their fingers caught in the hinge.

Pinched fingers are very common at this age, and trust me when I say this that as a parent, you want to prevent pinchings as much as you can!

So it’s probably good practice to get your doors secured by the time your little one is showing signs of crawling – according to Baby Center, this usually happens between seven to ten months.

Things To Consider When Baby Proofing Your Doors

We use doors a lot. Especially in and out of bedrooms, bathrooms and living areas. So there’s a few things to think about before installing your childproof lock.

Is It Convenient?

While your childproofing product needs to be strong enough to keep out your toddler, it still needs to be functional enough for you to use regularly throughout the day.

If it’s annoying or you’re literally struggling to use it, then it might be time to try something else.

Is It Still Practical In Case Of An Emergency?

If there’s a fire or some other emergency, you should be able to quickly and confidently get through the door. Make sure the lock or device works properly and isn’t prone to faults.

Would A Baby Gate Be Better?

Some parents find that a baby gate works better for certain areas. You can install them in doorways, replacing the need to shut the door and attach a lock.

One good thing is you can leave the door open and see into the room – some parents find that closed doors can make a small house feel even smaller.

How To Babyproof Your Doors

There’s quite a few different contraptions available.

You might even find that some designs work well on one door, but not another. Plus, they might serve different purposes – one might prevent children from getting their fingers caught in the hinge, while another might keep the door fully shut.

With this in mind, you may need to mix and match to meet all your babyproofing needs.

Let’s take a look at what options you can choose from.

Finger Protection Strips

This type of product is designed to protect fingers from getting crushed in the hinge side of the door.

They’re basically long pieces of plastic, which you install over the inside gap of the door. Working like a cover, they prevent fingers from getting caught.

Great for babies and young toddlers (as one to two-year-olds are most likely to get their fingers caught in the hinge side of the door). But, they obviously won’t stop fingers from getting trapped in the handle side, because that’s not their purpose.

Also, some products are made for very precise specifications – e.g. some will only work on doors that open to a maximum of 110 degrees.

Door Stoppers

These are curved, c-shaped devices that fit snug against the door, stopping them from fully shutting. It doesn’t actually lock the door, just prevents the door from slamming.

It will protect finger injuries from the handle side of the door, but not the hinge side.

The great thing is they’re easy to use – you just position them onto the door, and use it as normal, with no special technique needed.

However, this obviously won’t stop children from moving between rooms, as that’s not their purpose.

Door Handle Covers

These nifty locking devices literally cover the door knob or lever, almost like a shell.

Type #1: Knob Handles

If a toddler tries to turn the knob, the door knob cover will turn freely around the knob, stopping it from unlatching the door. Meanwhile, an adult will be able to grip it properly using access holes, or a special grip, in door knob safety covers.

Type #2: Lever Handles

If it’s a lever cover, it should have some kind of lock that can be clicked by an adult to allow it to open or shut. Meanwhile, if your child pulls on the lever, the cover will be locked in place, stopping the lever from working.

Flip Locks

These security locks are great for doors that lead out of the home, offering childproofing and extra protection from intruders.

They screw into the doorframe. You simply flip the catch in towards the door, to stop it from opening, and flip it back out to open.

By installing it high enough, it means that even if your child can reach the handle to unlock the door, this latch will keep it from opening.

They’re great because they’re easy to use and offer extra security.

However, if your partner or an older child comes home and tries to get in with the key, you’ll have to come and flip the latch to let them in.

Top Locks

These devices are made of two pieces – one sticks to the door and the other sits inside the frame at the top of the door.

When the door shuts, the two pieces lock together. For an adult to open the door, you simply slide out the catch and the door releases.

They’re handy because they’re designed to attach to the top of the door, so your kids can’t reach them. This is especially relevant if your kids are getting taller, older and figuring out how to work the babyproofing handle locks.

However, if you’re a short person (adult that is) you may need to use a wand to be able to reach the device when unlocking it.

A Suggestion For Those Planning To DIY Baby Proof Their Doors

Some parents swear by the towel method.

Basically, you throw a folded towel over the top of the door, close to the hinge, and this stops it from fully shutting.

Obviously, this doesn’t solve your problem if your priority is preventing your child from entering that room, but it will help protect their little fingers from getting caught in the door.

As always though, it’s important to remember that a DIY method isn’t guaranteed. A proper babyproofing product (or a combination of products) would potentially provide greater peace of mind.

Involve Your Children In The Safety Process

Childproofing locks and contraptions are great, but accidents can still happen.

So the best thing you can do is teach your children about the risks of doors. Sure, your six-month-old might look at you like “What are you talking about lady? Why are you pointing at that big wall thing that moves? Hurry up and give me my milk already!”

But if you keep repeating it as they get older, it might make a difference.

For example:

  • Explain to them why slamming a door could hurt them or a sibling.
  • Educate them on why they shouldn’t leave the house without an adult.
  • Teach them that places like the garage or laundry are no-go zones.

As they get older, this will hopefully make them more cautious. At the least, it’s worth a try.

Wrapping It Up & Why Supervision Is So Important

Lastly, it’s important to remember that the best way you can protect your kids is to keep an eye on them and implement as much safety tips as you possibly can!

We know. It’s a bit of a no-brainer, but it’s always worth repeating that you can’t always completely rely on products to child proof your house’s interior doors and exterior door.

The risk is that childproofing products can let you fall into a false sense of security. Sure, they’re a great help, but accidents do happen, and any device can fail for whatever reason. So, always be vigilant, as best as you can.

And remember, you think that childproofing  doors is hard? Wait until they’re teenagers and they’re climbing out their windows and shimmying down the drainpipes at night!
