For parents of newborns seeking more peaceful sleep, the Red Castle Cocoonababy is an ergonomic nest designed for use from birth (starting at 2.8 kg) up to 3 months of age. Its enveloping, semi-fetal position mimics the sensations of the womb: the baby feels soothed, startle reflexes are limited, and sleep becomes deeper. The high-resilience polyurethane foam returns to its original shape without restricting the child, preserving their freedom of movement and encouraging natural motor development. The included tummy band reinforces this sense of security with gentle pressure on the abdomen. The 100% cotton cover is fully removable and machine washable; designed and made in France.
