Where did my LO’s sleep go 😩

Please tell me I am not alone.

I am so so tired 😭

All of a sudden, the past week my LO who is soon to be 6 months and is EBF will not for the life of me sleep well.

She sleeps in my bedroom in her cot. She wants to be on the boob 24/7 and wakes up 2-3 times a night and even nursing wont settle her. I have to get up and rock her and sometimes i can be up rocking her for hours on end. When my husband takes over, she still wont settle unless rocked constantly by him.

I dont know if I should do sleep training because I dont want to spend money on it to have it not work.

Due to this I dont look forward to night times, it gives me anxiety from the thought of having to go through the same struggle every night.

Please any advice. She wont self soothe, if I try to let her cry it out she is hysterical. I tried the gentle approach and everything else under the sun but no luck.

Just want my evenings back for me time and some sleep :(

Also just an example of what I mean:

She goes to bed a 8pm every night, sleeps for 1hour and then shes awake screaming/crying. I go in there to settle doesnt work, I end up nursing her and when she is asleep and i remove it from her she wakes up. We then rock her for 1-2 hours until she is asleep, put her back down and she is restless the whole night, wont sleep and keeps rolling no stop (which wakes her as she rolls into the cot rails) Last night she woke up at 12am and the did not sleep until 3pm which then she proceeded to be restless the whole night 😩
