My LO is almost 3 weeks old and I am losing my mind... According to Baby Connect she is averaging 12 hours of sleep in a 24 hour period She is extremely fussy and goes long stretches during the day where she will be awake for 2 to 3 hours.

Everything I have read says she should be sleeping 16 to 18 hours. Based on our last Dr appt she is gaining weight. When she is awake she is not happy and is impossible to settle. Any suggestions/tips?
