DD, nearly 4, is suffering from impaction and overflow. She is on Movicol (only day 3 so no major explosions yet). The soiling is getting bad, to the point that knickers are needing to be changed (and thrown away) throughout the day and the poo is seeping though when she sits down. She doesn't want to be in pull ups and even if she did I think that would be a backward step. Has anyone in this position found a way to deal with this? I have googled pant liners but haven't found anything satisfactory yet.
