You can try "lighting" effect.
At day time, make sure the house is bright enough and switch on the light if necessary to make sure the baby know it is day time now.
At night time, you must switch off the light or just maintain a table lamp (dim one) and the baby will know it is night time for sleeping.
It is a natural sense for baby to feel day time and night time by lighting even before delivery.
