Doors are everywhere in a home, and for a curious toddler they can be both an invitation and a hazard. A door that leads to a bathroom, a laundry room, or the outdoors can hide risks ranging from drowning to falls. At the same time, the door itself, whether it is made of glass, swings on hinges, or folds in an accordion style, can cause injuries. Using the right safety devices and habits helps reduce these risks, but no product replaces close supervision.

Quick summary: Sturdy door knob covers and locks can keep toddlers out of dangerous rooms while still letting adults open the door quickly in an emergency. Pay attention to glass doors, swinging doors, and folding doors that can pinch fingers, and always keep bathroom and laundry room doors closed.

Door Knob Covers and Locks: What the CPSC Says

According to the U.S. Consumer Product Safety Commission (CPSC), door knob covers and door locks can help prevent children from entering rooms and other areas with possible dangers. The CPSC’s childproofing guide explains that these devices can help keep children away from places with hazards. The agency stresses that the door knob cover should be sturdy enough to withstand a toddler’s tugs, yet must allow a door to be opened quickly by an adult in case of emergency. No device is completely childproof, the CPSC reminds caregivers; determined toddlers have been known to overcome or disable them. That means door knob covers are one layer of protection, not a fix on their own.

When choosing and installing these products, look for designs that adults can operate without difficulty. The CPSC’s broader advice on safety latches and locks, which applies to cabinets and drawers, also holds true for door hardware: the device should be easy for an adult to install and use, but sturdy enough to withstand pulls and tugs from children. For more on how these items fit into a whole-home approach, see our guide to childproofing products explained.

Glass Doors, Swinging Doors, and Folding Doors

The American Academy of Pediatrics (AAP) highlights several door types that deserve extra attention in a home with a toddler. In its home safety tips for families, the AAP notes that glass doors are particularly dangerous because a child may run into them. The advice is to fasten them open if possible. Swinging doors can knock a small child down, and folding doors can pinch little fingers. The AAP suggests considering removing these types of doors until a child is old enough to understand how they work.

If removal is not practical, caregivers can look for ways to secure the door in an open position or add cushioned edge protectors to nearby furniture to soften any impact. The same AAP guidance reminds families to check for furniture with hard edges and sharp corners, such as coffee tables, which can be especially hazardous when a child is learning to walk. Products like corner and edge bumpers, mentioned by the CPSC, can help reduce injuries from falls against sharp edges.

Keeping Bathroom and Laundry Room Doors Closed

Water safety is a major reason to keep certain doors shut. Safe Kids Worldwide advises that after bath time, caregivers should immediately drain the tub and keep toilet lids closed. The organization also says to keep doors to bathrooms and laundry rooms closed to prevent drowning. The AAP’s guidance for children ages 1 to 2 years echoes this: keep the bathroom doors closed. A toddler can drown in less than 2 inches of water, the AAP notes, so denying access to these rooms is a critical step.

The AAP’s bathroom safety tips suggest a latch on the door at adult height so a child cannot get into the bathroom when you are not around, and say any lock on the door should be one you can unlock from the outside. Its drowning prevention guidance also mentions safety latches or doorknob covers to keep bathrooms closed.

Hotel Room Safety: Using the Deadbolt

When traveling with a toddler, the door to the hotel room becomes a safety checkpoint. The AAP’s holiday travel tips recommend that families use the deadbolt so a child cannot slip out of the room alone. The same advice suggests doing a “safety crawl” to check for choking or poisoning hazards that may have rolled under beds or dressers, and to move cords from lamps, TVs and phones out of reach. Keeping the bathroom door closed and considering a portable toilet lock are also part of the travel safety routine. For a full list of travel precautions, see our toddler travel safety checklist.

Doors Leading to Pools and Spas

Backyard pools pose a serious drowning risk, and the door that connects the house to the pool area is a key barrier. The CPSC states that most toddler drownings occur in their own backyard pools. To delay a child’s access, the CPSC recommends that doors heading to the pool should have self-closing, self-locking door mechanisms or door alarms. After each pool use, the barrier should be reestablished so that a child can access the pool and spa only when an adult is supervising.

The CPSC lists other barriers such as power safety covers, pool alarms, self-closing and self-latching pool gates, isolation and perimeter fences, and pool covers. The AAP describes a fence at least 4 feet high on all four sides with self-latching gates. The CPSC’s pool safety guidance reminds caregivers to always check the pool first if a child goes missing.

Toy Chest Lids That Pinch

Not all pinching hazards come from room doors. The AAP’s parent checklist for making a baby’s room safe points out that the best toy chest is a box or basket without a lid. If a toy chest does have a lid, it should have safe hinges that hold the lid open and do not pinch. The chest should also have air holes in case a child gets trapped inside. This advice fits the broader theme: any moving part that can close on small fingers deserves a careful look.

A Practical Door Safety Checklist

Use the points below as a walk-through guide. They are drawn from the CPSC, AAP, and Safe Kids Worldwide recommendations.

  • Install sturdy door knob covers or locks on doors to bathrooms, laundry rooms, basements, and any other room with hazards. Check that an adult can open the door quickly in an emergency.
  • Fasten glass doors open or remove them temporarily if a toddler is learning to walk and run.
  • Consider removing swinging doors and folding doors until a child is old enough to understand how they work, or secure them in an open position.
  • Keep bathroom and laundry room doors closed at all times. Use a door knob cover or a latch at adult height to prevent a child from opening them.
  • When staying in a hotel, engage the deadbolt and do a safety crawl to spot small objects and cords.
  • Ensure any door that leads to a pool or spa has a self-closing, self-locking mechanism or a door alarm. Reestablish the barrier after each use.
  • Inspect toy chests for lids that can pinch. If a lid is present, confirm it has safe, non-pinching hinges and air holes.
  • Remember that no device is completely childproof. Active supervision remains the most important safety measure.

Frequently asked questions

Do door knob covers work for all types of door handles?

Covers are made for different kinds of handles, so check the manufacturer’s instructions to confirm it is compatible with your door’s knob or lever. The key requirement is that the cover is sturdy and allows an adult to open the door quickly in an emergency.

At what age can I remove door knob covers?

There is no set age. The AAP suggests considering the removal of swinging and folding doors until a child is old enough to understand how they work. A similar principle applies to door knob covers: keep them in place until you are confident your child can safely navigate the rooms beyond the door and will not enter hazardous areas unsupervised.

Can I use a door knob cover on the front door?

Door knob covers and door locks are meant to keep children out of areas with possible dangers, and the outdoors is one of them. The AAP’s drowning prevention guidance suggests safety gates, door locks or doorknob covers to keep a toddler from going outside without you knowing, and its travel advice specifically recommends using the deadbolt in a hotel to prevent a child from slipping out. The same logic applies at home: a deadbolt or a high-mounted lock may be a more secure option for an exterior door, as long as adults can operate it quickly in an emergency.
