A friend of mine's daughter has major red flags. I told her a year ago, she rationalized and brushed it off.
My friend has gone internet-dark for over two weeks now, since just a couple of days after her daughter's second birthday. Normally she is posting photos of her kid every two days on average, and at the very least responding to email. I sent one a week ago; nothing.
I'm basically assuming at this point that her daughter had her two-year checkup at the pediatrician, and my friend got told something she didn't want to hear. But I can't help her if she won't talk to me, dammit (the email I sent was innocuous, basic stupid update about our first day of school.)
Denial: it's better not to have it.
