Just that.
We’ve tried everything (I think?!)
Seen the doctor who prescribed Senokot but to be honest I do actually think some of this is behavioural. He can’t be bothered to go to the toilet when he feels the urge (he’s actually admitted that in the past!) The senokot does make him go, but he tries to ignore that and ends up with a messy accident 
That said, he has said that he “doesn’t always feel it”. I was thinking of constipation and poo leaking round etc (yes, have been on the ERIC website, as well as spoken in great depth with a paediatrician).
I’m absolutely at my wits end with this. Can anyone offer any ideas? Please??!!
