A baby sleeping bag with legs, 2.5 TOG can be practical for toddlers aged 18 to 24 months who turn over, crawl or get up during the night. Unlike a traditional sleeping bag, a design with feet gives your child more freedom to move. But colour and price shouldn’t be the only things you consider. Fit, warmth rating, material and safety features all matter.
The 2.5 TOG rating indicates how warm the sleeping bag is, but it doesn’t replace checking the room temperature and what your child is wearing underneath. Lightweight to medium-weight nightwear is often suitable with a sleeping bag for 16–20°C. The right combination can vary depending on your child, the room temperature and the manufacturer’s guidance.
A sleeping bag that’s too warm can be just as unsuitable as one that’s too thin. Check the bedroom temperature regularly, and don’t use blankets or other loose bedding inside the sleeping bag.
A sleeping bag with feet should fit well around the body, neck and arms without feeling restrictive. Openings that are too loose can slip out of place, while tight cuffs can restrict movement. There should also be enough room around the crotch and legs, especially if your child wears a bulky nappy.
The stated height is usually a more useful guide than age. For example, the XL size of the Vowia model is designed for a height of 89 to 101.5 cm and a body weight of 11.8 to 15.5 kg.
Cotton feels comfortable, but care requirements can vary depending on the filling and construction. This can affect everyday use and how long the sleeping bag lasts. Before buying, check:
A cotton baby sleeping bag with polyester filling may lose its shape or warmth if cared for incorrectly. Always follow the manufacturer’s instructions.
A warm winter sleeping bag for babies with a 2.5 TOG rating is designed for cooler rooms. Always consider the TOG rating alongside the recommended room temperature. A 2.5 TOG model may be suitable for 16 to 20°C, provided your child isn’t wearing overly warm clothing underneath.
Check your child’s neck or chest to see if they feel warm. Babies’ hands and feet can feel cooler, so they aren’t a reliable guide to body temperature on their own. If you’re unsure, follow the manufacturer’s guidance and take your child’s individual needs into account.
When choosing a sleeping bag for an 18–24-month-old, your child’s measurements matter more than their age. The neck and arm openings should fit securely when fastened, without causing pressure marks. When the sleeping bag is fastened, your child’s head must not be able to fit through the neck opening.
When comparing sizes, check:
If two sizes are available, don’t buy a sleeping bag ‘to grow into’ if this means the neck opening will be too large.
An OEKO-TEX baby sleeping bag indicates that the textiles have been tested to the relevant standard. This is information about the material, not a medical claim. According to the product details, the Vowia sleeping bag is made from 100% cotton on the outside and inside, with a polyester filling.
A sleeping bag with a 2-way zip can make nappy changes during the night easier. It’s useful if the zip can be opened from the bottom and there’s a fabric guard at the chin. You should also check whether the manufacturer provides information about EN 16781. This European standard covers requirements for baby sleeping bags, including fit and construction. Always check the information for the specific product.

Before using the sleeping bag for the first time, wash it according to the care instructions. When dressing your child, guide their arms and feet fully through the openings provided. The zip must be closed and shouldn’t rub against the neck or chin.
For the Vowia model, a maximum temperature of 30°C on a gentle cycle or hand washing is recommended. Leave it to air dry, and don’t tumble dry, bleach or dry clean it. Before each use, check the zip, seams and cuffs for damage.
Don’t use a sleeping bag with a baby blanket or quilt. Continue to place your child on their back, in line with general safe sleep guidance for babies. Stop using the product if it’s damaged.

According to the product information available, a 2.5 TOG model is intended for temperatures of around 16 to 20°C. Choose your child’s clothing underneath to suit the room temperature and their individual needs. Don’t use additional blankets.
You can’t determine this by age alone. Measure your child’s height and compare it with the manufacturer’s size chart. The XL Vowia model mentioned here is designed for 89 to 101.5 cm. The neck and arm openings should fit securely when fastened.
How long it can be used depends on your child’s growth, the fit, how it’s cared for and the condition of the material. Choose a suitable replacement if the neck or arm openings become too tight, the legs are noticeably restricted, or the seams or zip show signs of damage.
