My DS has just turned 4. We managed to get him potty trained over Christmas just gone, and not having to send him to nursery in January really seemed to embed it for him. He was taking himself for both wees and poops at home to the potty. He's started back to nursery and won't use the toilets there. He's had three accidents all poops in the two weeks since starting back and he's also stopped taking himself to potty at home too! He's got good control so I know he's holding in wees while he's there but poos are obviously another matter. Teacher says to just keep persevering but I'm worried that he's backsliding on what he's learned at home. Any advice really welcomed!
