Thought I'd write a positive success story post about how it can improve and what I've done to help my daughters soiling/constipation. She's 4.5 years old and has been on movicol roughly since 2. Her brother is 3 and has never had any issues, ever. She started withholding after she was potty trained and in turn this lead to constipation and what I think was a stretched bowel. Cue numerous episodes over the years of having some weeks completely clean and then most other weeks dirty pants every 1-2 hours. I tried changing her diet (she's always been very good with fruit and veg) changing her drinks, her poo habits, the way I go about things, disimpacting, everything. She's been on 1 movicol sachet a day maintenance for a year now and it stuck at that. Recently I was at my wits end and decided to try two new (and slightly obvious) tactics. 1) cut out dairy from her diet whilst keeping the calories, and 2) triple her fluid intake. Now while she did drink, she's more of a sipper and would happily go all day only drinking 100-200mls. I believe this was a major contributing factor. Last week I sat her down and said she will have a cup (150/180mls) of anything she wants at breakfast, snack, lunch, snack and tea times. And she did! She was sensible and chose things like diluted squash, fruit juice, soya milkshakes, smoothie, but she did drink and my god it's made a hell of a difference. She's averaging 800-1100mls per day now. I think the lack of proper dairy has helped too, she's having soya most things and doesn't seem to notice or care. She has now been days and days going for a poo (or two!) properly per day, of her own accord, no soiling, peeing more and her appetite and temperament has improved. So please try these things before seeking any more medical help!! I also tried to be very positive and laid back about it all whilst keeping a close eye on everything without seeming to. Hope this helps someone!
