Hi Anne,
I remember not being able to write a thing when I was pregnant or had babies, but around the age of 16 months old (with both children) I suddenly discovered the urge to write again. My daughter had a three hour nap each afternoon, so I was able to get stuff done then but my son never slept for more than an hour (day or night!) so nothing got done.
I think this is your new, creative and energised self coming out! Hope we can help you to nurture and sustain it
I'm sure you know this already, but the most useful thing to do it to join one or two of the groups and post/comment on work. There are specialised groups for different interests = poetry, short stories, writing for children (much the best, hint hint!).
