“Are their legs ok in this sling?”, “why is the wrap leaving marks on my baby’s legs?” and “is it
okay for my baby to wear a sleep suit in a baby carrier or sling?” are questions I often hear from
new parents. It can be understandably concerning, particularly if parents are new to baby
carriers and aren’t sure exactly how their child should be sitting.
When answering these questions there are two things to think about – your baby’s positioning
and their comfort. So let’s look at how to check their position and the fit of your sling, and think
about how what your baby wears and the temperature can affect their comfort.
A correctly fitted sling will support your baby’s legs in a spread squat, mimicking their natural
position. This supports the legs from knee pit to knee pit and can aid the optimal development
of their hip joints, encouraging the formation of a deep socket joint. There’s lots of anecdotal
evidence to suggest that minor hip issues have actually been helped by carrying in a wide
based sling, and studies have shown that in cultures where babies are primarily carried from
birth in a spread squat position the rates of hip dysplasia are very low.

So by positioning your baby carefully in this spread squat you can help their development as
well as avoid any issues.
Babies can sometimes get red marks from their clothes or a sling, which does worry some
parents understandably. But babies do have delicate skin which marks easily.
If the mark disappears quickly and doesn’t seem to be causing any discomfort, there’s nothing
to worry about. It’s like us getting a sock mark or waking up with pillow lines on our faces.
One thing to check is that the panel of your sling, or fabric of the wrap, is sitting in your baby’s
knee pits, that the weight is on their bottom, and that their lower leg can swing freely. The
tendons located in our knee pits protect the blood supply so by checking the pressure isn’t on
their legs and that any fabric is sitting in the knee pits, we can ensure their comfort.
Your baby may get some red marks behind the knee where fabric bunches, especially if they
have bare legs, but like a sock mark this should not cause any issues and disappear quickly.
If you notice any discolouration on their legs (a blue or purple tinge) it’s likely that your baby’s
weight is on their legs rather than their bottom and it’s being caused by the pressure from the
edge of the fabric. A pelvic tuck and scooping their knees up will prevent this from happening.
The advantages of a good pelvic tuck
As we discussed above, the way a newborn tucks their legs up, or an older baby sits on your hip
with their knees above their bottom is ideally how a sling will support your child along the thigh
and into their knee pits (in the ‘spread-squat’ position). If you place your hand under their thigh
and scoop their knees upwards this tilts the pelvis towards you, placing the weight down into
their bottom and tail bone. By lifting the knees it also helps take any pressure off the legs.
Choose a sling that’s suitable for your child’s stage of development
Check your sling is age appropriate. Newborns can be quite curled up after birth so a sling that
isn’t going to be too bulky and have too much fabric around their legs will provide the most
comfort. If you’re using a carrier choose one that can cinch or adjust to fit from birth without
over-extending those little newborn legs. With a wrap, think about using single layer carries or
variations such as a lexi twist. Ring slings are a great option for young babies, they can be quick
to use and the single layer of woven material moulds around them, offering good support.

As your child gets older they may outgrow the knee to knee position if you’re using a carrier as
the panel may no longer be wide enough. However, when they are walking they no longer need
the sling to support all the way into the knee pits, as their hip joint is fully developed. Ideally, you
want the fabric of the seat to reach at least two-thirds of the way along their thigh. This will help
keep their legs comfortably supported in an M shape. At some point it will be more comfortable
for both of you to size up to a toddler carrier.

How clothing affects your child’s comfort in a baby sling
It’s important to dress your baby appropriately for the temperature. In cold weather, you may
need to add some leg warmers or use a babywearing cover to protect their legs from the chilly
air. In warm weather be mindful to dress babies down to avoid them overheating.
Whatever they’re wearing, remember that when your baby is in the sling in that ideal position
with their knees above their bottom, any clothing on their legs will ride up. Denim material or
clothing with large seams may be uncomfortable on their legs if they’re in the sling for an
extended period of time.
The same applies to any footed item of clothing, like sleepsuits. If a sleepsuit bunches up it can
squish toes. Often people advise against dressing babies in sleepsuits if they will be in a sling,
but this isn’t especially practical advice especially for newborns!
You can easily avoid any pressure on toes from sleepsuits by dressing your baby in
generously sized suits and pulling the material away from their toes when they’re in the
Babies will tell you if they’re unhappy
Babies will let you know if they’re uncomfortable so if they seem perfectly happy then they’re
likely to be comfortable. If they don’t seem content it could be a positional or comfort issue, or
something else entirely. Read more about What your baby is trying to tell you in the sling.
