Sleep help

My baby is 5 months old. Almost 6 months. I’ve recently started sleep training her. She goes down great around 7:30-7:45 p.m. I feed her at 7 pm. With our nightly bath and lotion rub down. She’s swaddled and I have a noise machine. Our little routine seems to work. BUT Two hours after she goes down she wakes up crying because she’s hungry. And I give her a bottle while she’s in bed. Propped up with a blanket. And from then on it’s like every two hours sometimes less she wakes up screaming and I can’t console her until I give her another bottle. So, is she actually hungry or is the bottle a clutch. What can I do to stop the waking so often. I’m so sleep deprived. And I live in an apartment so I know the crying/screaming has to be a lot for my neighbors. I’m starting to get a little desperate for help. I woke up today to her screaming and I just wanted to cry lol. I know. I’m so dramatic. But, I’m just so tired. 🥲 Any advice would be much appreciated. I should mention my baby has bad eczema and is constantly itchy. I know some days she’s just uncomfortable.
