My son (3.5) had his adenoids removed last week and his tonsils reduced. The consultant said they were "pretty massive" and were already seeing changes to his sleep (sleeping with mouth closed, breathing through his nose). I've read about behaviour improving after removal but I wonder if anyone has found this? My son has suspected ADHD and can be impulsive (more so than a regular 3 year old) and he is always tired. Has anyone experienced changes? I'm trying not to get too optimistic but at the same time I'm so hopeful that things get easier for him.
