Parents easily understand the importance of monitoring every aspect of their babies' lives. In order to assure the child's physical, emotional, and mental well being, parents are involved in feeding, sleeping, diapering, soothing, and teaching. Parents assume (correctly) that it is their responsibility to be so involved.
As their infants grow and develop, parents may actually find it difficult to appropriately relinquish some of those responsibilities. For example, one of the important lessons a parent has to learn at the baby's first birthday is to allow the child some independence as the child learns to feed herself.
Parents often feel a constant internal struggle between the appropriate monitoring of children and involvement in their activities versus allowing developmentally appropriate independence.
