Answer:
Human faces
Step-by-step explanation:
Infant simulation means the activities that stimulate or arouse your baby's sense of sound, sigh, taste, smell or touch.
It can improve the baby's memory, nervous system development, attention span and curiosity. Babies as young as four or five months can recognise emotions in people's faces. They are able to pick non verbal signals that we use during communication such as smile and raising an eyebrow.
So, the doctor would suggest her to decorate the room with human faces.
