The foot pieces are connected to the harness with straps who control the position of the hip. The harness has to be on 24 hours a day during the initial period of treatment as decided by the orthopedic surgeon. One can change the child's diapers without touching the belts and straps. A bath is not possible during this initial full time treatment period. A firm mattress , no pillow.
Small babies have to be placed on their back, unless there a medical contraindication to do so.
Don't pull on the blankets, a light quilt could be proposed. If the problem is unilateral, turn the bed in such a way that the affected hip is on the side of the wall, so that the child will not have a tendency to turn on that side to look around. Nothing under the harness. Socks stopping at the knee level and not tight. No pants, no shorts, no panties.
