I'm sure you are tired of hearing this.......! But hang in there! You surely can't go any more than another 24 hrs or so. You definetely sound like your body is doing the work, and you will have your reward soon. I can remember feeling like "Am I really having a baby here, or is this a really bad practical joke!" I know you can't wait to hold your little one, and he will be here very soon! Hang in there, he's coming! He will probably come really fast, because you are so well practiced! We never do know why our bodies play tricks on us, do we?
I'll be praying for you and your little one, for a safe and healthy delivery. God Bless!
