So she’s been a great sleeper at night since 2 months. She goes to bed around 9-10pm wakes up around 4-5am for a bottle and back to sleep til about 10am. And has some naps throughout the day. But lately she’ll wake up stay awake for an hour and back to sleep, all through the day and sleeps at night too! She is 3 months and a little over a week old. Is it a growth spurt? Should I be worried? Anyone else going through this? Her next appt is at 4 months she didn’t have a 3 month appt..
