19 month old n waking at night!

I need some type of help! My lo has not slept through the night since 6months old. She wakes through the night for a bottle and once she gets it she would go right back to sleep. The last 3/4 nights have been horrible. She wakes and I have to soothe her back to sleep by carrying her and even then when I put her back down she wakes up right away! It takes me about 30/40 mins of that to get her back down. I’ve tried the cry it out method a few months ago but she makes herself sick so I gave up on that. Advice? Anyone going through something like this? I’m the only one that gets up for her so this is really kicking my butt
