Hello! My 9.5 week old is really struggling to sleep. Last week he slept 4 nights of 6 hour stretches, asleep by 10:30, up at 4:30 to eat, and back to sleep for another 3 hours. This week has been a total nightmare. Won’t go down until 1:30, up every 2.5 hours. And isn’t sleeping more than 5 hours total at night. Tonight he’s been up every 2 hours and can’t seem to fall asleep. I’ve been up since 1 and it’s now 3:30. Any ideas? He’s not very fussy like he usually is with growth spurts. Mama is struggling!
