Kell its so tough when you have a baby that likes to party in the wee hours! Your doing a fantastic job! You have made no mistake in loving your baby and choosing not to let her "cry it out". I thik our DH dont really understand sometimes. My DH would say just let hime cry because he didnt understand the consequnces, he now knows after me nagging him to read the science of paretning lol
I am sure this will pass but its hard when you have no sleep and a crying baby! Have you tried co sleeping? This may help for the time being? Also she may have only just realised she is alive! so she may have become sensitve to everything?
DS did go through this but settled after we began co sleeping, he is just loves to be near me like most babies. But this doesnt always work for everyone! there is a light at then end of the tunnel!

Please folow your instincts and do what you think is right for your and bubs! Good luck xxx
