We need sleep!!!

Adalyn will be 8 months old on Saturday. We are going on month three of waking up at least 5-7 times a night. My husband works all day and I’m a stay at home mom with a four year old as well. It’s really taking a toll on everything, relationship, health, sanity. How do I get her to sleep!? She eats great all day. She is just fussy and is good again after I give her the pacifier. She does have a bottle around 1am which I don’t mind if she didn’t wake up all those other times. I’m one desperate mama.
