This guide is for you if...
✔ You've had or are having this issue
✔ You're wondering if something is wrong
✔ You want to consider your options
✔ You're just curious
✔ You're thinking about changing your carrier
Have you ever taken your baby out of their carrier and noticed their legs are looking a little red? Perhaps you've spotted red or blotchy marks around their thighs and immediately wondered:
"Is my carrier too tight?"
"Have I positioned my baby incorrectly?"
"Am I hurting them?"
First of all, don't panic, try and be diplomatic...
There are a few different reasons you might notice redness after babywearing, and not every red mark means something is seriously wrong. However, it is always worth stopping and checking what's happening, (a fitcheck for example could prove really valuable) rather than simply carrying on and struggling if you are worried about comfort.
Take baby out and have a look
If you notice your baby's legs changing colour while they're in the carrier, take them out and have a good look.
If it's jut like sock marks then there probably isn't too much reason to be concerned, if it's rubbing or looks sore then it's time to have a think about the carrier fit. Check whether the redness settles and whether your baby seems comfortable.
You're looking for more than just colour. Pay attention to:
Swelling
Coldness
Unusual colouring
Marks that don't settle
Signs that your baby is uncomfortable
Any obvious pressure points
How do baby's legs react when held in a similar position in arms, or seated in a chair?
If you're worried about your baby's condition or the colour change doesn't settle, and you're concerned, do seek medical advice.
Could the carrier be causing pressure marks?
One possibility is pressure from the carrier, the way it has been adjusted, and the way in which baby is positioned. We want the weight on the bum (good pelvic tilt can help with this, and the hold of that position will depend on your sling-type).
A carrier needs to support your baby securely, and be tightened correctly, but that doesn't mean every part of it should feel tight. The fit should allow your baby to be comfortably supported while maintaining an appropriate position. This is particularly important around the thighs and knees. Check your carrier waist settings... which leads me on to the point below.
Check your baby's leg position
When babywearing, your baby's thighs should be appropriately supported rather than hanging unsupported from the carrier. Equally checking if the legs are overspread (is fabric coming past the knee pits) and does your carrier adjust to widen, narrow to hold the knees in a better M shape.
For many carriers, you'll be aiming for a supported, comfortable position where the baby's knees are higher than the level of their bottom, with narrow-based carriers this won't be possible. so these have a shorter shelf-life because legs dangle and over time will be less comfy on you. There is nothing wrong with narrow-based carriers, but I would say the Bjorn Mini fits best - a lot of the other dupes do not offer a good newborn fit.
The exact fit will depend on your baby's age, size and the carrier you're using, so always follow the manufacturer's instructions as well as appropriate babywearing safety guidance.
Check the carrier isn't too narrow
As babies grow, the carrier that fitted beautifully a few months ago may no longer be adjusted correctly. This is one reason it's important to reassess your carrier as your baby grows. If the carrier panel is too narrow or isn't providing the intended support, it may change how your baby's weight is distributed. If you're unsure whether your baby has outgrown their carrier, have a look at this blog here.
Clothing can make a difference too
Sometimes the carrier isn't the only thing creating pressure.
Bulky trousers, thick seams, socks or other clothing can sit underneath straps or fabric and potentially create pressure points, the same can be said with lack of clothing.
For babywearing, thin and flexible clothing often works best, allowing the carrier to support your baby's body without unnecessary bulk. If you are confident little one's positioning is good, you could try threading a muslin into the base of the carrier and hanging down at the sides to see if the marks stop.
Check the rest of your baby's position
Leg position is only one part of a safe and comfortable carry.
Remember:
T – Tight: Your baby should be held securely against you.
I – In view: You should always be able to see your baby's face.
C – Close enough to kiss: Your baby's head should be close enough to kiss.
K – Keep chin off chest: Your baby's chin should not be pressed down onto their chest.
S – Supported back: Your baby's back should be appropriately supported.
When should I get help?
If you keep noticing redness every time you use a particular carrier, it's worth getting someone to look at your fit rather than simply accepting it as normal. A small adjustment can sometimes make a surprisingly big difference. If your baby appears to be in pain, has persistent redness, swelling, unusual colour changes or other symptoms that concern you, and you are sure that this is because of your carrier then checking in with a consultant could be really helpful to eliminate things and try other options if needed. If you are on the verge of buying a new sling – here's why I recommend trying options via your local sling library first.
Final thoughts
Seeing your baby's legs go red can be worrying, but it doesn't necessarily mean you've done something wrong. Take your baby out, check what's happening and reassess the fit before carrying again. If you're unsure, getting some hands-on help can be invaluable. A babywearing consultation gives you the opportunity to look at the whole carry together and work out whether the carrier, adjustment or positioning needs changing.
Sometimes it's just one small tweak that makes everything feel much better. Happy Carrying,
Emma
