Sorry ladies, I forgot to mention that I already use a dummy and she has a CD player that plays some soft lullabys. Even if the dummy is still in, she still wakes up . She also feeds 4 hourly so just one 40 min sleep every 4 hours just isn't enough. Sometimes I'm lucky enough to get her down a second time in those 4 hours, but not always.

Just don't know what to do anymore .
PinkLilly....like I said my DD went through a really strange stage at 4.5months. She wasn't like it for long but NOTHING I did settled her. Tried music, wrapping, dummy (didn't like it), everything you could think of. Did you get a hold of the "Wonder Weeks" book...perhaps someone in here can tell you if they go through a stage at 16 weeks??? I hope it gets better soon...
