Try a baby carrier, like from manduca. Then you just walk with them, until they calm down. Do household things, ect. or actually take a short (or long) walk outside. And maybe be conscious about your breathing when caring them, if you are stressed out(why is she not calming down!), they notice it and it does not calm them.
