How to get baby to sleep longer between feeds

Kayla
My daughter is on SMA comfort milk, I tried her on hungry baby milk but she just drank it like the normal one, no change apart from constipation! She wakes up about 5 times in the night for a bottle but doesn't finish them and wakes up like half an hour later to drink some more. I'm getting pretty much no sleep. All she wants to do is sleep in my arms and if you put her down, sometimes she stays asleep but sometimes she'll wake up and cry. Plus, every single morning Ava will wake up at 5:30 and mostly do a poo. How on earth do I get her to sleep during the night? I have no clue what to do anymore
