Baby sleeping on tummy

As good and vigilant parents, we all follow the recommended and widely accepted guidelines for safe baby sleep that at their core is placing baby to sleep on her back.


No one knows for sure what causes SIDS, we do, however know of several risk factors that can be associated with the syndrome - amongst them:


Inhalation of carbon dioxide,

House dust mites and breathing obstructions.

But what do we do when our baby grows and develops and begins using their new found mobility to turn from front to back - doing so in their sleep...

On this topic there is a wide range of written data and it is a concerning topic for us parents (and rightfully so), there are also a wide range of opinions by medical professionals as to what is the best course of action. We will not get into this debate, we leave it for each parent to choose his preferred course of action.

The challenge is that we cant always be there by her bed,  we need our sleep as well (however short a sleep it may be) - if baby rolls to her stomach in her sleep we can only try and make sure she has the safest sleeping environment while she sleeps on her stomach and until we notice and can roll her back. Such a safe sleep environment includes adhering to the safe sleep guidelines and making sure her stomach sleep is the safest it can be, one way we chose to do so is using Numu.

The Numu mattress reduces some of the known risk factors:

  • Allows for free breathing through the mattress even with sleeping with face into the mattress. This will be SAFER with Numu! 
  • baby sleeping on tummy
  • Prevents accumulation of carbon dioxide
  • Prevents overheating
  • Prevents build up of house dust mites

Thereby, Numu supports a safer sleeping environment for your baby

Some of these properties of Numu were mentioned by the American Academy of Pediatrics, in their report on SIDS and other sleep related infant deaths 2016: 

"Certain crib mattresses have been designed with air-permeable materials to reduce rebreathing of expired gases, in the event that an infant ends up in the prone position during sleep, and these may be preferable to those with air impermeable materials. With the use of a head box model, Bar-Yishay et al341 found that a permeable sleeping surface exhibited significantly better aeration properties in dispersing carbon dioxide and in preventing its accumulation. They also found the measured temperature within the head box to be substantially lower with the more permeable mattress, concluding that it was due to faster heat dissipation. This finding could be potentially protective against overheating, which has been identified as a risk factor for SIDS. Colditz et al342 also performed studies both in vitro and in vivo, showing better diffusion and less accumulation of
carbon dioxide with a mesh mattress."
