I just can't clean her without a shower. She soils between 1 and 6 times a day. She's on Lactulose, and her poo is always soft but she still does it in her knickers most of the time.
The main problem I have is that it gets into her vagina every time and it's a nightmare to get out with wipes. The other day, I had to try in a public lou and anyone would think I was trying to kill her! She won't do it herself. She does sometimes have a go, but she can never get it all out. She also has very sensitive skin and gets sore within an hour or so.
We've had to cut our days out short, or even stay at home. 
She is home educated and loves being out and about but it's almost impossible without a shower.
Does anyone have any tips I could try when out and about?
She's started complaining that it hurts when she wee's too. I'm wondering if she might have a UTI. Her behaviour has also been far more manic than usual. (And that's saying something!)
I'd really appreciate any advice.
