So Aviannah was sleeping great through the night since she was about 2.5 weeks. She slept for 5 hours stretches. She's now 6 weeks old and the past couple nights have been crazy. She wants to stay up all night, eat, fussing occasionally, coo, smile, and stare at everything. Is this temporary? maybe a growth spurt? Or do you think she got her days and nights mixed up? Just weird. Because about a week ago she did the same thing for a couple days then started sleeping through the night again.
