Crib training.. please help!!

My daughter will be a year old in June. She has slept in bed with us since she was a couple months old. She still wakes up multiple times at night and still nurses, no bottles whatsoever. I’m able to get her from bed to crib after she falls asleep but she only lasts maybe 3 hours in her crib before she’s back in bed with me. I tried letting her cry it out but she will cry for hours no matter how tired she is until I pick her up. She also likes to chew on her crib so she messes up her crib and gets paint in her mouth which Isn’t good. Dad is over her sleeping with us and I want our space back. I know we would all sleep so much better I just don’t know how to get her to sleep in her crib for longer than 3 hours. Please help me!!

Any tips on weaning so she doesn’t wake up wanting me throughout the night would be greatly appreciated as well 😁
