Not done backreading but I wanted to respond to this:
I hate the thought of anyone 2 years and older.
Don't write those kids off just yet!
My son just turned four last month. It was right around this time that his mom texted me one night. Paraphrasing what she said, but:
Her: "We have the sweetest son ever."
Me: "I know. What did he do this time?"
Her: "I was crying on the couch. He brought me the roll of toilet paper and wiped my tears, and asked why I was crying. I told him I was crying because I was sad, and he told me don't be sad."
All that, from a little boy diagnosed with autism, who has difficulty with speech, general communication, and understanding peoples' feelings.
