My nearly 3 year old hates pooing away from home and has always held it in. It's never progressed to more than 3/5 days at a time so not been much of an issue but was told to use lactulose when that happens. (Never made any difference tbh(
We've now moved in with family for a few months while my husband is away and it's every 4/5 days, dancing around, clearly avoiding the urge every few hours it comes. She's so much happier when it comes and is never in pain while passing. It just doesn't seem like regular constipation. High fibrous diet, plenty of water.All seems psychological?
