He has never had formed stools, seeing GP every 2 weeks now and Paed once, back again after 3 months which will be mid July (2 weeks now). Been on Movicol nearly 3 months, not much joy - been up and down dosage wise - 2, 4, 6, 8 then 2 for a few weeks, then another high build up and down to 4, then another high build up and down to 2 again, now up to 3. We are having some success in the past month with him feeling the need to go, and making the toilet, but still will soil afterwards and more often than not just soils himself without a toilet visit. I really don't think it's constipation - he's never had a hard tummy, movicol is doing nothing except giving him mad cravings for salt. What is usually the next step a Paed will take? What else can it be?
