I have been since day 7 but i wouldn’t say it’s comfy! Nurse said it was fine to whenever you feel OK doing it though….. i’m so sick of lying on my back! I’ve started getting my V Pillow and wrapping it all around my body and inbetween my boobs so i can lay sort of on my side, it hurts though! God knows if i’ll EVER be able to sleep on my front again! xx
