DS4 has ASD, is deaf and is non verbal. He has always been a selective eater. He will eat fibre (fruit and vegetables), is not hugely keen on meat but we get it in somehow and will drink Ribena and fruit juice all day long. What he has always been bad with is poo. The days between poos are stretching to about 10 days apart now. I have a job getting medicine into him and have had to resort to suppositories a few times when he's been feverish.
Any of you have a DC who is awful with poo, and what do you do to encourage bowel movements. I'm getting quite desperate. Seeing his paed tomorrow and also the GP to see about a prescription to help him. How I will get whatever into him, I don't know. 
Anyone out there who can help me please?? Thanks.
