My daughter is three in April. She's always been very regular at going to the toilet. Once or twice a day. We started potty training in August 2016 and it went well. Sje understood what she had to do. By Xmas she was fully trained in the day. Then she got constipated and didn't poo for 4/5 days. When she managed to go it was huge and it hurt her and made her bleed.
Since then she's held in all her poos because she's scared it will hurt again. Of course after 4/5 days it's big again and it does hurt. We've tried to explain that if she lets it out everyday it'll be fine.
We've taken her to the Drs and been given movicol and lactolose. But she's withholding probably 10/15 times a day and each time lets a tiny bit out meaning lots and lots of changes.
It's become so readily for our family. She's not the same happy girl she once was. Everything I read is so negitive and I feel this might go on for years.
