It is completely normal for a person that has died to release vomit, bile, urine or faeces. You may want to wash and care for the person yourself. It is easiest to place the body on a board, a door or something similar. Prior to bathing push down on the bladder region gently to release any urine. Use two people and a sheet to help you give the person a sponge bath. Use cold water as heat speeds up decomposition. You can use soap, shampoo and a hair dryer (briefly) if needed. Bring the body to the top of the board with one person supporting the head while the other uses a basin to wash the hair. Make sure to dry the body with towels, being quite gentle so as not to damage the skin.
Dressing the person can be quite difficult. It is recommended to release some of the rigor mortis by moving the arms, elbows, hips and knees of the person a few times. You will feel their joints soften, making it easier to put clothes on. Some ideas to assist include cutting the clothing off when removing. You can also cut new clothing at the back and tuck them in under the body to easier dressing. You can use cloth to wrap the person if you do not want to put clothing on them.
