Two days before the second national Lockdown in the UK, Ergobaby announced the release of their first ever anti-microbial carrier. But what does this even mean? Should you get one? Is this something you need?
This is one of those rare moments where my past job collides with my current job. As many of you know before I had my son I was a scientist. Specifically, I have a MRes in Infection and Immunity and a PhD in Immunology. So it really is one of those moments where I am assessing this carrier not only with my Carrying Consultant hat on but also with my Immunologist hat on.
The first thing to consider is what does anti-microbial actually mean? Something that is anti-microbial is something that can kill or limit the growth of bacteria and fungi. Note kill or limit the growth of – not all anti-microbials kill bacteria and fungi, some simply stop or slow growth down. This means you can still get transmission or infection from something with this agent in it. You’re just less likely to because bacteria or yeast will grow much more slowly so there will be less present on that surface.
Anti-microbial IS NOT the same as anti-viral. Generally agents that are anti-microbial are not effective against viruses because viruses propagate in a totally different way to bacteria and fungi. Bacteria and fungi grow on surfaces, whereas viruses can not grow with out a host. For them it’s just about surviving in a transmittable form on a surface and not about growth. This is one of the reasons that, generally, surface transmission is less of an issue with viruses, few viruses truly transmit via surfaces. And the quality of the surface has a huge impact with viruses – shiny surfaces that can hold droplets are far far more effective for viral transmission than something that droplets soak into like fabrics. Fabric generally has extremely low viral transmission. Even if a virus can survive on the fabric, because of the way water soaks in and dries out on fabric, it is extremely difficult to catch a virus from touching fabric. Any fabric, not just specially designed fabrics, ANY FABRIC. Which is great news for baby carriers in general.
The second thing to consider is what the anti-microbial agent is and the mechanism by which is works. So for the Ergobaby carrier released last week, the agent is Silver ions. Silver has long been known to have anti-microbial properties. Bacteria can’t grow on its surface and its non toxic for humans (two reasons it’s popular for jewellery). Specifically it is the silver ions that are toxic for, and kill bacteria by binding to some of their essential cellular components preventing the bacteria from performing basic reactions required to live. Hence silver is used a lot in hospitals, from silver coated tubes and catheters to antibiotic creams used to treat burns. Silver ions are even added to plasters and bandages.
So potentially adding them to a baby carrier, may have certain advantages. If your carrier is prone to getting very smelly. If you use it frequently while working out with Carifit or someone, frequently spill stuff on it and don’t wash it – then silver ions may help keep bacteria from having a field day on your carrier. Although, I should say, the effectiveness will depend a lot on the concentration of the silver ions added to the carrier and on how long they remain in the carrier with washing etc. It’s worth noting that silver infused bandages are not washed and reused (but generally incinerated) so I have my reservations about the longevity of this protection. Likewise the Ergobaby anti-microbial carrier is the same price as the regular carrier, so this makes me a little suspicious about the concentration and how much silver ions have been added. There is no information about this, so it is difficult to tell how this compares with the amount added to bandages and plasters etc.
However, while this may potentially be a pro if you do find your carrier gets smelly very fast, my experience over the last 7 years working with parents tells me most parents don’t find this. In fact, I find most parents will wash a carrier long before it starts to smell. Certainly if it gets dirty or they spilt something on it. And for the parts of the carrier that get chewed on and possetted on there are simple solutions like suck pads to protect the chewed on parts of the carrier. Allowing you to regularly wash these while keeping the carrier clean and dry.
So ultimately when it comes to keeping bacteria at bay, most parents actually don’t find this a problem.
And when it comes to keeping viruses at bay – something that is on all of our minds at the moment in the middle of this global pandemic – silver ions have absolutely no effect on CoV-Sars-2 (the virus that causes Covid19) or any other virus because, as I mentioned above viruses replicate by an entirely different method to bacteria. And surface transmission plays a much smaller role compared to transmissions via droplets in the air.
So do I think you need an anti-microbial carrier? No, no I do not. For all the reasons above. Fabric is a lousy transmission surface for viruses and the chances of you or baby catching a virus off any fabric baby carrier is extremely small. You don’t need a special fabric to keep you safe.
For bacteria – if you don’t like washing your carrier ever and are prone to getting it wet, damp and filthy then maybe you would see a benefit, but if you are like most people and wash your stuff if it’s dirty then I doubt you’ll notice any difference buying an anti-microbial carrier versus buying a normal one. I would simply recommend buying a pair of suck pads instead!
My personal opinion with my both my immunology and babywearing hats on, is that this is all an example of clever marketing. Getting you to think that you need something that actually, for most people, won’t make a noticable difference. I do sell the regular material Ergo Omni 360, but I won’t be buying into this gimmick and retailing any of the silver ion ones.
If you don’t have a carrier yet and think silver ions are cool and would like to own a carrier containing silver ions, then please do be my guest and buy one. Do so with my total, unreserved blessing. However, this article is for the people who maybe already own a carrier then started reading the marketing and thought “OH NO! Did I make a mistake? Should I have bought this instead? Will my baby be safe?” Or for the people who were about to buy something else that they wanted more but the marketing made them pause and now they aren’t sure.
For all these people – you don’t need an anti-microbial carrier to keep your beautiful baby safe. Just carrying them close to your body in your carrier, or whatever carrier you choose that fits you both well, is keeping them so safe and so nurtured and so loved. And that is all that matters.
