The Lovenest new born head support is a small soft but firm heart shape made from dense contoured foam. Developed by a paediatrician it helps prevent positional plagiocephaly or 'flat head syndrome' in babies 0-4 months. The Lovenest takes the pressure off the single spot the baby favours whilst still allowing baby to move their head. Combining the Lovenest with a few simple recommendations from product designer, paediatrician Dr Maidenburg (provided with the Lovenest) will help considerably prevent the "flat head' condition. Features of the Lovenest Newborn Head Support- Comfortable and supportive: baby's head lies naturally at the centre of the Lovenest. Balanced and safe: cradled and gently directed, baby's head no longer rolls from side to side. Unlike a pillow, the covered, lightweight foam does not lift the baby's head. Freedom to move: Baby can move their head at will. Well distributed and gentle: baby's head is prevented from solely resting on the occiput (or back of the scull). Use when ever baby is on his/her back including when in pram, car seat, on play mat etc Dimensions 23 x 24 x 3cm Use from birth to 4 months. Use only when baby is on his/her back. Machine washable.
