Baby sleep help🥴

Literally asking for any advice/suggestions that could work because I’m absolutely exhausted.

My little girl is 9 months old next week, for the last 3 months she’s been waking every other hour between 7 - 2. Goes back down after a feed at 2:30 then up again at around 5. From about 2 weeks old she’s had her same routine, bath bottle story and in bed for 7. She physically cannot stay awake past 7 because she’s so tired. Sometimes she goes down awake but sleepy and sometimes she goes down asleep if she can’t make it through her feed. She honestly use to sleep like a dream until she hit 6 months and now she just won’t sleep at all. She’s never really been a napper, in the day she will have an hour around 10 and 45 minutes in the afternoon. I could leave her in her cot to self settle, go for a walk, a car ride she just will not nap and will not give in. Just this morning she was at 1:45 and stayed awake until 5:45. She eats a very balanced diet, always takes her milk and she’s always very content during the day.

I feel like I’ve tried everything, recommended Bath soothers, plug in aromas, controlled crying, sitting by her cot and moving further away each time. Shushing and patting. At 3 this morning I’m finding myself online googling sleep experts. I’m due back to work next week, it’s having a massive impact on me emotionally (I’m tired all the time and can get teary so easily) constantly questioning what I’m doing wrong, why she won’t sleep. I honestly love her with every piece of me but I’m desperate for her to get a good nights sleep as well as us. I know it’s a “welcome to parenthood” and I understand that. I just need some advice 🤞🏼
