The Lulla doll is suitable from birth. 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. Many people are using the doll for older children who are faced with troubles sleeping or calming down. We even heard about a few parents that like to use the sound to help them fall asleep and we had reports of the doll helping dads to stop snoring! Elderly people with Alzheimer's have also used the doll for added comfort.
