Yes. When a carrier seats your baby in the M-position: knees above hips, thighs fully supported.it supports healthy hip joint development. All hope&plum carriers are designed to achieve this position from the very first carry with no inserts required.

The M-position refers to the spread-squat seating position where your baby's knees are higher than their bottom and their thighs are fully supported from knee to knee. When viewed from the front, the baby's legs form the shape of an M. Pediatric hip health experts recommend this as the optimal position for babywearing.

The spread-squat position (also called the M-position) keeps the femoral head seated correctly in the hip socket during the critical window of early development. Knees sit higher than the bottom, thighs are fully supported from knee to knee, and the spine maintains a natural C-curve. This is not a marketing claim. It is anatomy.

Most carriers concentrate your baby's weight at the tips of your shoulders, creating pressure on the trapezius muscle. The Lark's patented wide cross-back straps distribute that weight across the upper back instead, specifically the rhomboid and upper trapezius muscle groups, reducing localized pressure and making all-day wear genuinely comfortable.

H-back straps run parallel from the carrier panel straight up to each shoulder, concentrating weight at the shoulder tips. Cross-back straps cross the wearer's back before reaching the shoulders, distributing weight more broadly. The Lark's patented cross-back strap design is wider than standard cross-back configurations, specifically shaped to spread load across the upper back rather than the shoulder tips.

Many parents find babywearing with a well-fitted carrier more comfortable than carrying in arms during postpartum recovery. The Lark's apron-style waist transfers weight to the hips rather than the lower back, and the cross-back straps reduce upper shoulder strain.

For C-section recovery or diastasis recti, we recommend consulting your care provider before babywearing. Our team offers free one-on-one fit consultations to help you find the most comfortable setup for your body.

The International Hip Dysplasia Institute no longer certifies or independently tests individual products. Their website now lists corporate sponsors at paid partnership tiers ranging from $25,000 to $500,000 over five years. We have chosen not to participate because we do not believe a paid listing is equivalent to product testing, and we do not think parents should have to wonder whether a logo means a product was actually evaluated.

What we can tell you is that every hope&plum carrier is designed to achieve the M-position and spread-squat seat that pediatric hip health experts recommend, using natural fiber fabrics that support rather than restrict healthy positioning.

All of them. Every hope&plum carrier is designed to seat your baby in the M-position from the very first carry. The best carrier for your situation depends on your baby's age and how you plan to use it. Take our quiz and we will match you.
