As this is a forum it's perfectly acceptable to discuss openly about what could help and what might be necessary. I don't get your anger towards those that feel there could be something more going on. For the record, our Dr suggested we get our little ones hearing checked as she was not a big speaker either. And guess what? Her hearing was an issue. She also refused to walk and he said it was her doing her own thing on her own time. She didn't walk until she was 18 mos. He wasn't a terrible Dr. He was right on. She's perfectly fine but still has a bit of hearing issues.
By the way May is Better Hearing and Speech month. So whether you like it or not there may be other people out there frustrated and having a hard time trying figure out how to help their kids. Some people will not be able to do it on their own due to circumstances beyond their control and it's nice to know they don't have to do all on their own. Please save your distasteful words for another month.
