6 month old won’t sleep

Alisha • Baby Kuritz #2 on the way 🥰

Help me... it takes me hours at night to get my little girl to sleep. Idk what else to do. It kills me to let her cry it out(which I tried last night and only made it 10 minutes). I rock her and pretty much get her to sleep and put her in her crib with her paci then a few minutes later she wakes up screaming! The other day it took me almost 4 hours to put her to bed... and I know she is tired. Please help if there’s any ideas you ladies have!

Update:

She takes great naps during the day! Every other night we do bath time and she immediately knows it’s bottle and bed time, but she still fights it! I mean arches her back and everything. I thought she was overtired so I tried putting her down at 7 the other night and still the same thing! We have a white noise machine every night for her. I will admit she is not on a strict routine so I will try and do a better job with that!
