Your child’s refusal to sleep in parents’ arms or in the pram could be the result of a sense of insecurity. She is probably used to sleeping in a quiet place with no outside sounds. You can only take her out of this habit with a lot of patience and gradual efforts. Some introspection may help in understanding if she is getting enough time for bonding with the mother. At this stage of infancy, children are going through a phase of attachment formation and it is necessary to form a trusting relationship with the mother figure before the child can get over separation anxiety.
