Help me!!

My 10 week old daughter SCREAMS like she's being murdered if she gets put down. I'm at a loss as what to do about it. I always make sure she's fed, burped, and changed before I try and let her cry it out for a little bit. Does anyone have any other suggestions or advice? It's my fault though lol I know she's spoiled because before, any little whimper she would make I would run and get her and she does co-sleep, we have created a monster!😩😓
