Fall,
Welcome to Elijah! I am so glad that you found him, that you and he found each other. It is a huge commitment and I'm sure the two of you (and baby-to-be) will enjoy each other for a very long time.
I like what you wrote about people wanting more and more of your time. I found the same thing, especially with my kids. I not only could never say 'No' to my kids, I would volunteer even more of my time. I truly believed it was what I was 'supposed' to do. And, had I given a portion of that time to myself, I would have been alright, but I didn't. I gave until I was empty, and then I fell apart. Looking back, I can't believe that I never thought giving time to myself was worthwhile.
