A baby sleeping bag will be perfect for toddlers who have already grown out of the cone. They cuddle and keep you warm all night long, even for actively moving babies. The sleeping bag is closed with a zipper (in 3/4 of the circumference of the sleeping bag), making it easy to change the baby even at night. In addition, the arm of the sleeping bag is fastened with a press stud, which also makes it easier to put the baby in and out.
