Bought in the middle of a very long night but never ended up using. Baby was too old for it. Wish I had this as a newborn! From the website- The award-winning Babocush Colic Relief Cushion holds your baby just like you do. If your baby is crying for more than 3 hours a day, they may have colic. The comfort cushion relieves gas, colic, and reflux discomfort through relaxing tummy time. The parent’s heartbeat & vibrations feature of the internal control box, simulates being held by you which means less crying, less pain, and a settled baby. The cushion encourages the strengthening of baby’s neck, back and torso and helps prevent flat head syndrome. Suitable from new-born to 6 months to ease the harsh transition from womb to real world. Machine washable lux-velour fabric with a 5 point quilted harness to hold your baby securely.
