My DS was a pita sleeper compared to DD and I had no idea what to do. What I realised is that I wasn't being consistent. I wasn't giving myself an opportunity to see if my methods were working, I'd just do one night and then chuck it in if it wasn't working. And I forgot about the basics.

Apologies if you are already trying or have tried this but are you feeding to sleep in a darkened room? Is your bubba warm enough? The constant waking in the wee hours could mean coldness? Maybe an extra wrap or blanket or long sleeve pj's? If you aren't well rested, maybe your milk supply could be suffering. You could try some RLT, fenugreek or activite drink a couple of hours before that final feed? At her age I would be feeding her each time she wakes but that's just me. I put a chair in DS's room and fed him in that chair until he settled and then put him in the cot and pat him off to sleep and then the cycle would begin again.

Good luck, it is such a hard run and difficult time - sleep deprivation sucks. Sending you guys some sleepy vibes.
