I have been there, done that and SURVIVED. My middle son tried to come prematurely (at 32 weeks just as his brother did). Labor was stopped using a medicine that made me extremely nervous. He wound up coming at term, but he was a very nervous baby -- looking back, I realize that he was probably addicted to the meds they gave me to stop labor. BUT he cried non stop for the first year of his life. He slept very little and screamed when he was not being held. I had a 17 month old and was pregnant by the time he was 6 months old. My husband traveled extensively with his work and we had recently moved far away from family and friends.
There were sove very trying times, I was exhausted much of the time -- but I am here to tell you that that phase was short lived AND my dear sweet Earl was worth every sleepless moment -- he is now a very handsome 26 year old that loves his mommy very much
Remember, this too will pass. For me a cup of hot chocolate, a good book and a hot bath (all at the same time

) was a short respite. Good luck!!!
