Cheers on your 6 month old. I am having a blast with my daughter. As for the insomnia ...what are some things you can do to relax? I think sometimes as new moms we are busy taking care of everything thing else ... especially the little one, that we forget to take care of ourselves. My big "me time" was a long, hot shower after putting my daughter to bed. That helped relax me and allowed me to sleep. I will confess though, I have become a light sleeper ... now I can hear my daughter opening her door down the hall. As for the dumb thoughts ... I am sure if we all compared notes, our random thoughts and panics in the middle of the night would make a great story! :}
Good luck and remember ... take care of yourself. You cannot be superwoman 24/7 - you need some TLC for yourself on occasion.
