Ds cracked wees on day 2, but is struggling with poos. He has been withholding and didn't poo for 5 days and was HYSTERICAL. He's now been prescribed movicol which is helping in that he's going once a day now at least but he dances around the potty for HOURS when he needs to go, getting on/off/on/off until he actually finally goes when he can't hold it any longer. How do I help him? It's totally ruling our lives at the moment.
