We've been sharing a bed with our daughter since she was about 4 months. She's always been a terrible sleeper, but it's gotten better when we put her in bed with us. She's 7 months now and we've had 3 nights of very little sleep. She literally tosses and turns all night and whines and cries out, almost like she just can't get comfortable. Is this a phase? Anyone else going through this? Is there anything I can do to get her back to sleeping more peacefully?
