This hits the nail on the head. Western society (esp in the US) has evolved in ways that just don't meet many of our emotional and psychological needs as humans.
I have a three year old daughter, and my wife and I don't live close to any family. I can absolutely relate to OP's isolation. I can't imagine having two kids right now. Fortunately, I do see a light at the end of the tunnel. Every few months she becomes slightly more independent or at least more capable of understanding and following directions. I've heard 5 is when you start getting some of your life back.
Anyhow, I need to get my kid dressed...
