Support/feeding cushions are generally filled with polystyrene beads. If you place your child in the centre of the cushion it will effectively make him feel cradled or “contained” in a small space but he will automatically remain in that posture - which will not necessarily be the right one. Leaving him lying in an incorrect posture for a few hours during the day or during the night is not recommended. Products made from beads can sag so parental surveillance is essential at all times. There is no substitute for the Cocoonababy® nest which has evolved through years of medical observation.
