My 3 year old son tore every page out of like 3 of his books.... Why? I'm so worried about this child after everything he's been through and I've also never had a 3yr old til now obviously lol. Is this normal? Do all or some kids do this? Or does it signal any kind of problem(s)? I think he may have ADHD or something, but idk? I have 3 kids yes but he's my oldest so I'm still experiencing new things lol. I'm so worried :/ ???
