I agree with Theresa your daughter is probably picking up cues from you and your husbands stress and anxiety that you probably don't even realize you have from time to time, let her sleep with you and be close and make her feel comforted it is a big change for her and just let her make some rules and feel a little bit in control of her sleep that is all she has left right now so you have to reassure her even if it is a little bit uncomfortable for you from time to time. When she throws tantrums just stop whatever you are doing or in the middle of her tantrum and just hug her and hold her and tell her it will be alright till she calms down, this might be hard to do because we always expect our children to behave but once again she just needs you to love her and know and feel that you love her the way a one year old can understand
Good luck...
