The Lulla doll is thoroughly safety tested to be suitable for newborns. However, it is not recommended to have loose items in a crib with a sleeping newborn from birth to 12 months. Because of this the doll is also designed to be a crib-attachment, with velcro straps hidden in a pocket on its back for easy attachment to most cribs, car seats, strollers and other carriers. The volume of the sound is 65dB making it safe for babies sensitive hearing.
