I'm so happy to see this post and know my DD is not a crazy baby! She is 4 weeks today but we having dealing with the same think for the last week. She had these symptoms a few days ago, got better and then yesterday and the day before all she wants to do is nurse.
She was taking 2 1/2 to 3 hour naps, now, if she is not on my boob I'm lucky if she sleeps 30 min at a time. It is EXAUSTING!! I was ready to give up on BF but I guess it would be the same thing with formula if it is a growth spurt.
Also, DD has started this new thing for about the last 4 days of not sleeping unless I am holding her. She used to sleep well in her rock n' play but now if I get her laid down I'm lucky if she stays asleep 5 minutes before waking up and screaming uncontrolably until I nurse her :/ Poor DH, anytime he tries to hold her she instantly starts crying. I can hand her off to him in a dead sleep and within minutes she is awake crying. He keeps saying she hates him, I feel so bad for him. She is kinda a daddy's girl so I'm not sure if this attachment to me is part of the growth spurt or what?
