there is no problem if the child is sleeping on the side or the child is sleeping on the tummy. the important thing is that if the child is not having any difficulty in breathing as well as respiration and digestion problem then you can continue to let the child sleep as well as give feeding in this position. but if you feel that the child is having regular coughing as well as breathing difficulty then you have to change the position of the child
