If you’re expecting your second child, or if you’re a parent of twins, here’s a truth no one tells you: the baby monitor you loved for your firstborn is now functionally obsolete.
The challenge isn’t just “watching” a second child; it’s “monitoring” them. This leads to frantic, non-solutions. Do you buy a second, separate monitor system and carry two parent units? Do you use a Wi-Fi camera and deal with the app-switching lag, battery drain, and eventual “app fatigue”?
The “two-child” problem isn’t about more cameras; it’s about smarter management. You don’t need two monitors; you need one system. You need a single parent unit (the “brain”) that can intelligently manage multiple cameras (the “eyes”).
The Feature You Think You Need: Split-Screen
When you shop for a multi-child system, the first feature you’ll see is “Split-Screen.” This is exactly what it sounds like. A monitor with this feature, like the Babysense Max View + 2, comes with two (or more) cameras and displays both feeds side-by-side on its single 5.5″ screen.
This is a great, necessary feature. As one parent of twins (“Horrible front elastic band”) put it, the monitor was “great… mainly due to the split screen.” It solves the visual problem completely.
But it creates a new, more urgent problem: You can’t hear both rooms at once.

The Feature You Actually Need: Audio Scan (SCAN Mode)
If you can only hear one room, how do you know if the other baby is crying?
This is where the “Split-Screen” feature proves to be a gimmick unless it is paired with Audio Scan (or SCAN Mode).
SCAN Mode is the true hero for parents of two. Here is how it works:
1. The monitor remains quiet, showing both video feeds.
2. The monitor’s audio “listens” to Camera 1 (your toddler’s room) for 15 seconds.
3. Then, it automatically switches and “listens” to Camera 2 (your newborn’s room) for 15 seconds.
4. It repeats this cycle indefinitely.
One user, Allison M., who had two children, perfectly described this: “I remember reading some reviews saying that you could only have sound coming from one camera, so I was worried… But turns out, that’s not the case. You can turn on scan mode and the sound will flip back and forth from each camera.”
This audio-scanning feature is the only way to have reliable audio coverage for two separate rooms without filling your own room with a constant, confusing din of white noise from two sources.
Case Study: An Integrated FHSS System
This “system” approach is where dedicated, non-Wi-Fi (FHSS) monitors often shine. Wi-Fi systems that rely on phone apps can be clumsy. As one user (V F) noted, “I switched from Eufy (a Wi-Fi system) and am so glad I did. This seamlessly integrates both cameras.”
A dedicated system, for example the Babysense Max View + 2, is built for this purpose:
* The Brain: The 5.5″ parent unit is the dedicated “hub.”
* The Eyes: It comes with two 1080p HD cameras out of the box.
* The Ears: It has the critical SCAN Mode to alternate audio.
* The Intelligence (VOX): A good system also combines this with VOX (Voice-Activated) mode. As user Demi Gresham found, “Using Vox mode to watch both the baby and toddler lets me watch both and hear the separate camera when noise is made.” This means the screen stays dark until one of the cameras (in either room) detects a cry.
For parents with growing families, these systems are also expandable, often allowing you to connect up to 4 cameras to the same, single parent unit.

When you’re shopping for your second child, stop looking at “baby monitors.” Start looking for a “multi-camera monitoring system.” Ensure it doesn’t just have split-screen (a visual feature) but, more importantly, has audio-scan (an audio-management feature). Your sleep will depend on it.
