As standard your hire fee includes Tracked 24 delivery. 

This means that it usually arrives the next day. However this is not guaranteed. For guaranteed next day delivery within the UK we would need to use Royal Mail Special Delivery. We are often able to do this if needed for an extra fee. 

In order to ask us to send your sling Special Delivery please phone us on 0800 6891251 between 09:30 and 14:00. Post is collected shortly after 14:00. We need time to set this up online, pack, manifest and print the paperwork and ensure the parcel is in the designated pick up location on time.

On some occasions we will be unable to send an order by Special Delivery, this includes where the order has already been dispatched, or when the person managing rental orders is not available. We will do our best to work with your request wherever possible.

Our article Why hire a sling or carrier?  covers this in detail.

If you know what you want that’s great! We can help you buy a sling if you want to buy new. If you want to buy preloved we recommend somewhere like Little Possums Preloved on Facebook. 

However, if you don’t yet know what you want, renting a sling or carrier can save you money. There are so many different brands, types and sizes out there it can be confusing to know what to go for.  Every parent and every baby have different sizes, shapes and comfort zones, so trying it out first makes sense. Just because a carrier worked for a friend, that doesn’t mean it will be the one for you, just as their favourite comfy shoes may not suit your needs!

If you rent something before you buy, you can find out whether it really suits you, your child and your lifestyle.  

Other families hire a sling or carrier for special occasion such as a wedding or christening when they would like something pretty, or to match on outfit or colour scheme. Buying a sling for an occasion like this may be out of budget.

Holiday or event hires Other families find that hiring a sling for a holiday, day trip or special occasion where their usual sling, or pushchair option don’t fit the bill. Hiring once a year, and being able to pick a carrier that is ideal for the environment, type of holiday, weather, and the age of the child may make sense if slings are only used fro 1 week a year. Children grow! Hire the ideal size for your child right now.

Some families like to try lots of different carriers because they enjoy trying new things, or because what they find comfy changes as their child grows. Renting can be a more cost effective way to manage this than owning a big selection!

Whatever your needs, we’re sure to have a sling or carrier to suit.

Our range

We have a huge range of carriers. Many local sling libraries cannot afford multiple twin carriers, preschool carriers,  or the bigger brand names. As we serve families throughout the whole of the UK we are able to offer a larger range of carriers, and have most carriers in stock or with a very short wait. 


We send the slings to you at your home (or work) address, so you can order from us without ever leaving your sofa. This may be ideal as local events are in person, and often limited to once a month, limiting your options. Getting to an in person event with one or more babies, or toddlers can be tricky, as can fitting in a trip around work hours. Hiring from us can be managed from your phone or computer.

Book in advance

If you know when you are going on holiday you can book in advance to be assured that the sling you need will be ready for you when you need it. Avoid the frustration of there being no cool version carriers available for your holiday by booking online from our rental catalogue.

We have several articles that can help you to choose a sling:

Help me choose
What’s the best sling?
Does my sling fit OK?

Please DO NOT wash our carriers. Some are delicate, and need special cleaning.  Ordinary detergents can damage carriers or shorten their usable life span.  Washing the carriers is part of our service. 

Please let us know if you are not happy with the condition when you receive it so that we can either instruct you what to do or rectify it ourselves. We understand that children may get the odd bit of food, such as chewed up biscuit, or posset marks on a sling. We ask that you only spot clean these with water only before returning the sling.

In the instance of heavy soiling, please contact us for advice.

Food, such as chewed up biscuit,  and posset marks are expected when carrying children, but please keep the sling away from anything that may stain permanently (tomato based sauces, greasy foods, oil, paint, pens, hair or make up products, nail varnish etc.), or anything that might damage it (scissors, velcro, keys in your bag, fire, etc.)

You simply pop the sling or carrier/s in the postage paid bag provided, affix the prepaid return label provided, and have it scanned in at a Post Office counter by 12 noon on the day before the final day of your hire to ensure no late fees will be owed.

If you have lost your return label just get in touch and we can send you a new one to print out.

If the sling that you have chosen to hire is unavailable for your chosen dates then you have a few options. 

Widen the search: Some slings have many patterns or designs, but are functionally identical. For example, all Tula Free-to-Grows will fit the same, so you could have a navy one instead of a grey one. Try searching for the name of the sling variety, rather than a specific design or pattern.

You can get in touch and ask when the sling you want is next available to hire, so you can book it for its earliest available date. Alternatively, if you need a carrier for a specific date, you can get in touch and ask for our advice on another suitable carrier that is available. 

Get in touch. Let us know what issue you are having. We are usually able to take payment over the phone, or offer another payment option. 

We suggest that you email us on, phone us on 0800 6891251 between 09:30 and 14:00, or message our Facebook page. We will aim to get back to you ASAP. If possible please provide us with a phone number so that we can call you to take payment over the phone.

In line with current advice that fabric poses little risk for transmission of Covid-19 hiring slings and carriers is generally very safe. Best practice means that items are quarantined for 72 hours between hires. This means that by the time a carrier was posted back from a client, and then out to another client there are very low risk of any form of transmission. 

We are practicing increased hygiene measures such as hand-washing, and are washing most slings after each hire. However, we are no longer washing every sling between every hire. 

We do wash every newborn twin sling, stretchy wrap, and newborn specific carrier between each hire, and any carrier that shows any sign or smell of use. 

We are happy to ensure that a carrier is sent out freshly washed if requested. Please get in touch to let us know. We may substitute your carrier for a different pattern if that one is freshly washed, to avoid a delay to your start date whilst we wash and dry a carrier, or we will amend your start date to reflect the later posting date. 

We ask that you DO NOT wash the carrier yourself. If you need to wash the carrier, please get in touch for advice on how to do this. This is to avoid damage to the structure of the fabric or elements of the carrier.

Link to the manufacturers’ instructions for our rental carriers can be found on the Manufacturers’ instructions page.

You are very welcome to take our rental slings abroad. Many of our rental slings are very well travelled. They can be really useful in the airport and on all parts of your travel. However, please be aware that if it goes in the hold and your luggage is lost you will be liable for the costs outlined in the terms and conditions of your hire as found on our Policies page.  We suggest that you keep the carrier with you, either wearing it, or in your hand luggage.

All carriers are extremely safe when used properly, however misuse can cause injury to yourself or your child.

It is your responsibility to ensure that you are using the carrier correctly and that your baby or child is safe at all times when using the carrier.

CalmFamily/It’s A Sling Thing cannot be held responsible for any accident or resultant injuries that occur whilst the carrier is in your care.

Carriers are checked for safety before they are sent out, but things can be missed, problems can develop, or carriers may be damaged during use or in transit. It is the borrower’s responsibility to check over the carrier before each use. Check all buckles, hems and seams ensuring that there are no tears, breaks, cracks or holes. If any damage is discovered, please stop using the carrier immediately and contact us. 

All hires are provided with a paper safety leaflet.  A link to instructions for all carriers can be found on the manufacturer’s instructions page where the Manufacturers make instructions available.

To familiarise yourself with basic carrying safety we would suggest that all customers read our Carrying safety article.

If you have any concerns about safety whilst using the carrier please stop and get in touch for assistance.
