Ideally - yes. In reality - I can walk my feet off and my 3 months y.o. daughter won't stop crying. Sometimes nothing but mommys tit helps (even if shes not hungry. A pacifier won't do either, no matter the model, if she needs her mom - she needs her mom)
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.
Did you try completely getting rid of milk protein for the mother? We tried this from advice from the nurse but they said for a week. It wasn't enough, it can take 3-4 weeks. Ask your nurse for help, there are other food you can give your baby while you wait for the milk protein to disappear from the mother. Milk protein allergy can be tested with blood tests too but is pretty invasive for a baby.
