Losing the will

Sh*t sleeper once, sh*t sleeper forever?

This is what I've been wondering about every day for the past 6 months, and where I get a day or so respite once a fortnight, this is not sustainable.

LO is 6 months Monday and has always been a terrible sleeper. But this is getting beyond the joke now. I am contemplating sleep training, even though I despise it, that's how tired and wound up I get about LG not sleeping.

We used to have 3 hours or so, hell, even 4.5 on a good day before she woke up at night. Now it's like every hour and a half, give or take half an hour. I'm exhausted to the point I fall asleep stood up.

Tried 'heavier' foods before bed, pushing the routine back by an hour, swaddle, darkness my old friend, everything by the book.

LO is breastfed and currently sleeping in a next to me crib flush against our bed as an extension, and I always try settling her back without feeding but that never works. Oh and I doubt she's hungry all those times she wakes because she just likes to bite down on my nipple at 3 am and yank it around like a ragdoll. She also likes to perform almost a full body slam repeatedly lifting her legs and banging it against the mattress.

She also only naps 30-35 mins recently during the day 3-4 times a day.

I'm happy for people whose babies sleep through but I hate hearing those stories as it makes me feel worse, alongside the scare mongering every baby article seem to write about how I must be 'intentionally keeping my baby awake and it's all my fault really'....

Shouldn't this be getting better? Transferring to own room and all that jazz? ....
