Answer: A. Maintaining a schedule and not following the child's lead.
When taking care of an infant, the most important thing to remember is that care should be based around the infant's needs. Option B adresses this concern, as it states that carers should pay attention to noise level and stimulation. Option C also encourages paying attention to the child by helping infants with special needs feel included. Option D, similarly, focuses on the child by providing a sense of security in the infants. However, option A does not consider the needs of infants, and in fact, prioritizes those of adults.
