Baby monitor for two rooms: siblings, twins and two cameras

A baby monitor for two rooms is one parent unit, or one app, that receives from two baby units: one in each child’s room. You need it when your children sleep apart and out of earshot – a baby and an older sibling, or twins who have moved into separate rooms. Before you compare screens, check the thing that matters most at bedtime: that you hear both children, and that an alert tells you which one woke. Twins who share a room can usually get by with a single unit.

Do you need a baby monitor for two rooms?

Only if you can’t hear both rooms from where you spend the evening. In the first months the question rarely comes up: the NHS recommends that your baby sleeps in a separate cot or Moses basket in the same room as you for at least the first six months [1], and the American Academy of Pediatrics (AAP) recommends sharing a room, not a bed, preferably for at least the first six months [2].

It changes once your children go to bed before you do. Typical setups:

• Siblings in two rooms: the baby in the nursery, the toddler next door or upstairs.
• Twins in separate rooms: often because they wake each other.
• One child in your bedroom, one in their own room: in the evening, while you’re downstairs, both are out of earshot.

If both children sleep in one room, one camera that covers both beds – or an audio unit between them – is usually enough.

Baby monitor for twins: one camera or two?

While twins share a room, one unit does the job. The Lullaby Trust, the UK safer-sleep charity, says newborn twins can share a cot in the early weeks, and that they need separate sleep spaces once one of them can roll and move about the cot [3]. That changes where the cots stand, not how many monitors you need, as long as both cots are in the same room.

A second camera earns its place when:

• the twins move into separate rooms;
• the cots stand so that one camera can’t show both well;
• you already have a monitor that takes an extra camera, and one child will get their own room later.

What baby monitor can show two rooms at once?

Video monitors that take two cameras show the pictures in one of two ways:

• Split screen: both pictures side by side or one above the other. You see both children at a glance, each in a smaller picture.
• Switching: the screen shows one room at a time. You switch with a button, or the unit cycles between cameras by itself – some call this scan mode.

Which suits you depends on how often you actually look. If you mostly react to sound, a split screen adds little; the alert matters more than the picture. Whether a camera is worth it at all is the subject of our guide to audio vs video baby monitors.

Can a baby monitor for two rooms let you hear both children at the same time?

That depends on the monitor, and it’s the question to settle before you buy. With two cameras and one parent unit, everything arrives on one device. Check the manual for three things:

• Do you hear both rooms at once, or only the one whose picture is on screen?
• Does each room trigger its own sound alert, even while the other room is displayed?
• Does the alert tell you which room it’s from? A beep doesn’t help much if you then have to work out which child is awake.

If you can only check one of these, make it the last. An alert that names the child is worth more than a picture of both: in the evening you don’t want to study a screen, you want to know which door to open.

Is there an audio baby monitor that can hold two baby units?

If you don’t need a picture, look for an audio monitor whose parent unit pairs with a second baby unit. The same questions apply as for cameras: can you hear both rooms at once, and can you tell from the alert where it came from? If the manual doesn’t say, ask before you buy.

What to check in a baby monitor with 2 cameras

• Range: a radio link has to get through walls and floors. If the children sleep on different floors, the parent unit has to reach both cameras from wherever you spend the evening. Test that before you rely on it.
• A warning when a unit drops out – for each room: a camera that has lost its connection must not look like a quietly sleeping child. Switch one unit off and see whether, and how quickly, the parent unit warns you.
• Extra cameras: if your second child will only move into their own room later, find out whether you can add a camera, how many the parent unit accepts, and what one costs. The consumer group Which? puts the overall price range at less than £20 for a basic audio monitor and more than £300 for a top-end wi-fi video monitor with several cameras [4].
• Placement: the US Consumer Product Safety Commission (CPSC) advises keeping monitor cords at least three feet from any part of the cot, crib or bassinet, and never placing a monitor inside a cot or on its edge [5]. With two cameras, that applies in both rooms.
• A dark, quiet nursery: nothing on the baby unit should glow or beep where your child can see or hear it.

Baby monitor for two rooms without Wi-Fi

A radio monitor with two baby units works without any internet connection, which makes it the right choice for a holiday cottage without internet; range is then the limit. A phone-based monitor works the other way round: distance stops mattering, but both devices need the internet. The trade-offs are laid out in non-Wi-Fi baby monitors.

Using phones as a baby monitor for two kids in different rooms

Instead of buying a set with an extra camera, you can use phones. Each child’s room gets a spare smartphone or tablet that listens and, if you like, films; your own phones receive. For a second child you don’t buy a second camera, you charge a second old phone – perhaps one you already have in a drawer. Our guide to using an old phone as a baby monitor covers setting one up.

When you compare apps, check whether they can monitor several children at once and tell you which one is making noise, whether several parent phones can receive at the same time, and whether they work only on your home Wi-Fi or over the internet as well.

Babyfino is built for this. Each child gets their own baby device, a spare phone or tablet in their room. Your phones show every child by name with their state – calm, awake or no connection – and an alert names the child it is about. Any number of parent phones receive at once. Whoever goes to a child taps “I’m going”: the others see who went and aren’t alerted again during that waking, for three minutes at most. If a baby device loses its connection, you’re alerted about ten seconds later. Babyfino works on Wi-Fi and mobile data, needs an internet connection on both sides, and is coming soon for iPhone and Android.
