The knee chest position in children can be a buzzword to one of two diagnoses.

The first one is Tetraology of Fallot in which children take the squatting knee-chest position in order to increase peripheral arterial resistance and thereby increasing the afterload and so they reverse the right to left shunt which helps them get rid of their cyanotic symptoms.

The second one is posterior fossa tumors commonly seen in children in which assuming the knee chest position will help them relieve the pressure off the back of their heads and minimizing their increased ICP related symptoms such as headache.
