DD is 7 mo and has never got over the 4 month sleep regression. Will rarely nap more than 40 minutes but she wants to have longer wake windows now and only 3 naps so she is usually pretty grumpy and overtired by bedtime. Will this ever end without COI? I've booked a sleep consultant, and seeing if I can get antidepressants from the GP for me, but it feels like there is no light at the end of the tunnel. My nipples are in pain from all the night feeds back to sleep (she just screams if we try any other technique). She feels too young for COI but this is unsustainable. Any positive stories out there from babies who just didn't learn how to sleep at first? Everyone else I know seems to only be being woken up every 3hrs or longer or is on antidepressants themselves...
