the dummy was replaced with a baby ( doll of her choice) she also has a cuddly ( blanket) that she has had since she was born, I think she wasn't ready for the dummy to go either but it has been gone for 4 weeks now and don't really want to take a backwards step and give it back to her now ;-(. Daddy's is dealing with some of the crying, hysterics, screaming etc but he works away so is not always around so I am left to deal with it 99 percent of the time.
"My husband decided she was old enough to go without her dummy" -- I suspect that your daughter is disagreeing with this decision. By the way, when you took her "dummy" away, with what comfort item did you replace it? My guess is - nothing - and your daughter is letting you know that she is not happy.
Maybe you should re-instate the "dummy" for a while and remove it gradually, instead of asking her to quit "cold turkey". Since this was Dad's idea, I hope that Dad (and not you) is dealing with her crying, hysterics, screaming, and not sleeping. Being a bit facetious there - sorry ...
