crying it out in crib

Jessie 🌛 • Celine 💕❤️
has anyone ever done this in order to get them to sleep in their crib? she fell off of the bed last night and this is the last night she will be sleeping with us. her doctor said it's okay to let her cry it out and said i need to try getting her into her crib and to stop letting her sleep at the boob or be rocked. 
so, how did you do it? i can deal with the crying, her dad is the softer one. i just want to hear other experiences and make sure i'm not letting her cry too much or what exactly i should be doing... 
i just tried it and her flipping dad picked her up right away. i'm kind of pissed because he complains he doesn't want her in bed and then does that 
sincerely, a mom who wants her WHOLE spot on the bed back. not half of her own spot...
