When you have a baby, you get used to suddenly waking up to screams and cries. It’s just a fact of having children that you have to adjust to. And while most of the time, you might find it annoying, other times? It’s actually a really useful thing to have around for your family.

Case in point, Kyle in Monique Ruppel, who woke one night to their daughter Celia crying. This is the sort of thing that they must have been used to, but there was an extra detail to this time. When Celia cried out the first time, Monique rose and put her back to bed. When Celia cried out again at 3 AM, her parents got up to respond – and found themselves dealing with the effects of monoxide poisoning. Luckily, the entire family was able to get out of their home in time, and are fine as of this writing.

So the next time your baby is wailing, pay attention. It might just be a good thing for everyone involved.
