My 6 year old had an x-Ray which showed she was full of stool. The doctor advised a 4day cleanse using ex-lax, miralax, and enemas. This is day one and she has had 2 doses of ex-lax, 3 doses of miralax, and 2 enemas and so far only clear liquid is being passed, no stool. Is this normal? She is also complaining of stomach cramping.
