Amber,

My son (who is now 7 years old and WONDERFUL) cried constantly too!  It was miserable.  Once he got medicated, he settled down (around 2 1/2 months).  I remember the frustration and saying "I love him because he’s mine, but I don’t like him".  We had no family near by at that time, and I felt like I was going crazy.  I did find that the vaccume cleaner noise and the "static" between the radio stations helped.  There were many evening that my husband would find me rocking a crying baby in front of 3 foot speakers with the static on!  Our son also wouldn’t sleep unless he was MOVING....so he slept upright in his wind-up swing for 3 months!  We’d get up every hour to wind the swing and then go back to sleep.   I would have your daughters levels checked.  I know exactly how you feel....I’ve been there!  Feel free to e-mail me!
