Oh god I've failed ds havent I? 
He is just turned 4 & starts school next week. And still can't wipe his own bottom.
We have tried & tried to encourage him to do it over the last few months & he will sometimes do one wipe but refuses to do more. He gets himself upset & is boking & saying he doesn't like it.
TMI but he always needs lots of wipes (minimum 5) & I am terrified he is going to just do one & end up with it up his back/all over his hands(happens often)/on his clothes when he is at school & his bum will still be covered in it & he'll be sore as a result.
Should we have started this much earlier?
How can I encourage him to do this by himself? Should I make his teacher aware even though I know they are not allowed to help?
