Had a casual chat with my sons teacher this morning to ask how he was getting on and teacher said he goes to loo a lot during lessons. He said he thinks this is work avoidance. He said others are doing this too. Teacher said he doesn't know him enough yet to determine whether this was normal for him or not. He doesn't have a problem with needing the loo frequently at home. Has anyone had any experience with this? Do they grow out of it? Is it a tactic to avoid lessons? I will ask him tonight why he goes so often but any advice appreciated.
