Comparison Baby Bjorn Move vs Baby Bjorn Synergy

— Kangaroo carrier. Kangaroo carriers are backpacks designed to carry children, allowing them to sit upright with their legs dangling out and arms moving freely. Unlike conventional backpacks, kangaroo carriers can be worn on the front, typically for older children with strong spines, although not recommended for long-term wear due to potential strain on the child's spine and legs, especially when facing away from the parent.

— Ergo carrier. Carrier for babies and toddlers. The device combines the advantages of slings and kangaroo carriers. Ergo carrier provides the baby with an anatomically correct position — the baby is on the mother's chest, and facing her. Like a kangaroo carrier, ergo carrier has in its design all types of straps, bridges and locks, which increases the safety of carrying the child, and also provides lumbar support, which provides comfort to the parent.

— Scarf. The classic sling is a long, durable piece of fabric that can be used in various ways such as a carrycot on the chest, a backpack, or a bag. It's suitable for newborns and older children, allowing for horizontal and vertical carrying with multiple attachment options. While simple and inexpensive, it requires manual tying, which may take some practice to master and can be inconvenient if adjustments are needed during carrying.

— Ring sling. A type of sling (see abo...ve), equipped with a fastening in the form of a pair of rings, between which one of the ends of the sling is clamped. The main advantage of this design is the ease of adjustment: you do not have to tie the sling manually and bandage it to change the position of the child or tighten/loosen the sling itself; all adjustments are made within a few seconds. On the other hand, models with rings are not as versatile as scarf slings. In addition, they are designed to be worn on one shoulder and the load on the parent’s spine is distributed unevenly; when the child grows up, this can create very significant inconveniences.

— Mei tai. The Mei tai sling is a cross between a kangaroo carrier and a scarf sling (see above). It has backpack-like straps, which makes it easy to adjust and eliminates the need to constantly re-tie the sling; Moreover, many models provide for carrying in both vertical and horizontal positions, and the design itself is much simpler and lighter than a backpack. In warm weather, a child in such a sling will not be as hot as in a scarf sling. At the same time, such slings are much less versatile in adjustment than scarves.

— Hiking. These devices are essentially hiking backpacks adapted for carrying children, worn exclusively on the back for optimal weight distribution during long-term carrying, ideal for activities like hiking. They often feature a rigid folding frame, typically made of aluminium, which can transform the backpack into a high chair. Unlike other types, hiking models have a wider age range, accommodating children under 5 years old.

— Sling pocket. A sling pocket is a modernized version of the traditional sling, designed for carrying the baby in front of the parent. It functions as a specialized backpack, worn over one shoulder or on the chest, providing maximum comfort for the baby with its shaped inner surface. Most designs allow for easy wrapping of the baby, making them convenient for both children and parents. However, they tend to be more expensive and less versatile compared to classic slings.

— Hip seat. A hip seat is a device designed for carrying a baby on your hip, providing support and comfort. It's suitable for older children who can sit upright, typically used from the age when the baby can sit independently. The hip seat resembles a wide belt with a shelf-like protrusion for the child to sit on, aiming to distribute the load on the parent's spine, reducing fatigue and preventing back pain. While it doesn't have straps, offering constant close contact between parent and child, some models include straps for added security.

— Chest harnesses. The harnesses are fixed with a chest band or strap. In this case, the harness will not press on the child's crotch, which increases the comfort of using the supportive harness.

— Crotch harnesses. In this case, the child is supported at the lowest point. The main advantage of this type of harness is the anatomically correct support of the internal organs. The disadvantage is the creation of pressure in the crotch area. Because of this, crotch harnesses are not recommended to be used for long periods of time.

— Strap harnesses. They feature adjustable height and width for the seating area, making them universal and customizable for each child. Equipped with clasped straps, their length can be easily adjusted to accommodate different body types. They come in designs with either chest or crotch harness configurations.

The recommended age range for kangaroos/slings is somewhat arbitrary, as children of the same age can vary in weight, height, and development. However, it provides a rough estimate of how suitable a particular model may be for your baby at different stages. The lower age limit, though, is more strict; for instance, if a backpack is labeled "3-12 months," it shouldn't be used for newborns as it's not designed for their needs and could potentially harm their bodies.

Now on the market are carriers designed for this age: from birth, from 3 months, from 6 months.

Lumbar support is primarily designed to provide comfort to the mother while carrying the child. Thanks to this belt, which tightens at the waist, carrying the child for a longer time will not bother. And all thanks to the best distribution of the load on the back.

Breastfeeding design. In this type of feeding, the baby is positioned in a reclined position, resting on the mother's thigh so that the baby's head is at breast level. Feeding a baby in a kangaroo/sling is easier due to the more comfortable weight distribution, and the device also hides the mother's breasts from the views of others.

— Cotton. Natural material based on plant fibers. Cotton is pleasant to the touch and quite durable, and it is also well suited for hot weather due to its permeability. Disadvantages include sensitivity to moisture (it gets wet quickly and takes a long time to dry), as well as difficulty in cleaning from certain contaminants.

— Polyester. Synthetic material. It is highly durable, considered hypoallergenic, easy to clean and quite resistant to moisture — it gets wet relatively little and dries quickly. On the other hand, polyester is much less pleasant to the touch than cotton and is less suitable for hot weather — the baby will sweat more.

— Cotton/polyester. A combination of the two materials described above in varying proportions. Designed to combine the advantages of cotton and polyester: more durable, more resistant to moisture and dirt than pure cotton, at the same time better suited for hot weather and more pleasant to the touch than polyester. The specific properties depend on the proportions of cotton and polyester, which can vary considerably from model to model.

— 3D (mesh). In this case, the term "mesh" refers to the structure rather than the material itself, resembling a coarse mesh as the name suggests. These models excel in ventilation, making them ideal for warmer weather as they reduce sweating for the baby. Typically made of s...ynthetic materials like polyester.

— Jersey. Knitted fabric can be made of pure natural fibers or a blend of natural and synthetic ones. It comes in varying densities and thicknesses, offering both lightweight and warmer options. However, its inherent elasticity and tendency to stretch make it particularly suitable for scarf slings (refer to "Type").

— Cotton fabric. A cotton-based fabric (see above) with the addition of other materials, sometimes synthetic. This increases strength, durability and resistance to creasing compared to the original cotton, while being pleasant to the touch, easy to clean and environmentally friendly.

— Linen. Linen slings and kangaroos are designed for use in the warm season. Linen is well ventilated and has excellent hygroscopicity. The main advantage of linen is the presence of bactericidal properties that prevent the development of pathogenic microbiotics. Additionally, linen fabric has a fairly durable structure. Such carriers are quite reliable and durable products. Usually used for older children whose skin has already become a little rough.

— Linen/cotton. In this fabric, the durability of linen is complemented by the softness of cotton. Cotton linen is predominantly a summer fabric. Such slings and kangaroos are well ventilated, they are hygroscopic and pleasantly fit the body. The ratio of cotton and linen can be different. Most often in the fabric is 50% cotton and 50% linen. But cotton is also found in the ratio of 70% cotton and 30% linen. The more cotton, the softer the fabric is to the touch.

— Cotton/silk. The cotton and silk based fabric is soft and glides perfectly. The mixture of cotton and silk gives the product pronounced hygroscopic properties, such fabric easily absorbs moisture, it is well ventilated. Slings and kangaroos based on cotton and silk have proven themselves in the warm season.

— Cotton/bamboo. Cotton and bamboo baby carriers combine the high durability of bamboo fiber and the softness of cotton. They are hard-wearing and pleasant to the touch. Cotton and bamboo based fabrics are characterized by good air permeability. Bamboo fiber gives slings and kangaroos increased resistance characteristics. At the same time, the material demonstrates pronounced bactericidal properties.

— Silk. Silk slings and kangaroos are ideal for summer use due to their moisture-absorbing and well-ventilated properties. Silk's smooth texture offers a pleasant sensation on the baby's skin, minimizing any potential rubbing. Additionally, they are hypoallergenic, reducing the risk of skin irritation. However, these products tend to be pricey and demand special care, including hand washing with specific detergents and careful drying due to technical challenges.
