Caregivers such as parent and day care providers desire to keep the infants under their care as happy as possible. One way that caregivers try to accomplish this is by modifying the environment of the infants as they analyze signals of their happiness, alertness and/or agitation. This analysis requires the caregiver to have enough time and opportunity to observe the infant's signals, and remember the behavior to detect patterns. This becomes additionally difficult when multiple caregivers provide care such as with day cares. Further, at times the caregiver may not wish to be in the same room as the infant, such as during naps, or during the night. |
