Our 6-year-old dd is beyond silly. She has had a tentative ADHD diagnosis but we are evaluating further. Meantime, life at home with her -- specifically when she's with her 4.5 and 3 yo siblings -- is borderline unbearable. Almost *every* interaction they have is about the word "poop," "stupid," "hiney" or some variation thereof -- and always at top volume.
Is this focus on silly words normal at this age? Do I just need to accept it as a dynamic between her and her siblings where they wind each other up this way? I don't hear her friends doing this, but as I said, it does seem to mostly be with her siblings.
Thanks in advance.
