The prince, who was voluntarily put in a medically-induced coma after being rushed to hospital with pneumonia, has been making good progress according to doctors.
Royal spokesperson Pierre-Emmanuel De Bauw said that the prince was in a "stable" condition.
Prince Laurent of Belgium
Laurent's health has improved and professionals at the Cliniques Universitaires Saint-Luc hospital in Brussels are now encouraging the 50-year-old to eat.
The prince's recovery appears to be going according to plan as doctors had said that Laurent was to be placed in a coma for up to 48 hours in order to give the antibiotics time to act against his pneumonia.
"An artificial coma would avoid the patient exhausting themselves by fighting against the life-support system," reported Belgian television channel RTL.
His wife Princess Claire, 40, who was born in Bath, England, has been at his side every day since his hospitalisation, while his elder brother King Philippe and Queen Mathilde have also shown their support.
Philippe visited his younger brother on Monday, while Mathilde went to see the royal early on Tuesday.
