In the M-position, your baby's knees are bent and sit higher than their bottom. Their thighs are supported and spread apart, so the knees and bottom form a shape similar to the letter M. This position is recommended for hip-friendly babywearing. Source: International Hip Dysplasia Institute
Leg position is only one part of adjusting a carrier correctly. Your baby's upper body also needs support, and they must be able to breathe freely at all times. Source: American Academy of Pediatrics
How can I recognise the M-position?
Look at your baby's position from the front or in a mirror: their knees are bent, their bottom sits lower than their knees, and their thighs rest on the carrier's seat. Their legs should not be forced into a straight position. Source: International Hip Dysplasia Institute
How to check your baby's position in a carrier
Follow the instructions for your carrier model when putting it on. Use these points to check the fit:
- Seat: Adjust the seat width according to your model's instructions. The seat is the part of the carrier between your baby's legs. It should support the thighs from one knee crease to the other. KOKADI: seat width explained
- Support: Your baby sits close to your body, with their back supported so they do not slump.
- Face: You can see your baby's face at all times. Their nose and mouth are clear of fabric and are not pressed against your body.
- Head position: Your baby's chin is off their chest. When carrying them on your front, they should be high enough for you to kiss the top of their head.
The advice on support and head position follows the NHS TICKS guidelines. Keep checking your baby's position while carrying them. Source: American Academy of Pediatrics
Why is the M-position recommended?
The International Hip Dysplasia Institute recommends carrying babies with their hips bent and their thighs supported, with room for the legs to spread naturally. IHDI: guidance on positioning
This does not mean that a baby carrier prevents or treats hip dysplasia. In its current statement, the IHDI explains that the available evidence does not show that any baby carrier causes or prevents hip dysplasia. If your baby has a diagnosed hip condition, follow medical advice when choosing and using a carrier. IHDI: current statement
Frequently asked questions
What should I check when carrying a newborn?
The carrier must fit your baby's size and support their back. Keeping their airways clear is especially important for young babies. If your baby was born prematurely or has breathing difficulties, seek medical advice before using a carrier. Source: American Academy of Pediatrics
Can a baby wrap support the M-position?
Yes. A correctly tied wrap can support your baby's thighs and allow their knees to stay bent. Using the wrap correctly is essential. Source: International Hip Dysplasia Institute Our wrap tying instructions show the steps for each technique.
