HI, I agree with Debinoz. I used to think that my lo hated being swaddled, but in retrospect I think that the resistence he used to put up was because he was overtired. It took ages to 'perfect' the 'art' ! but once I got it right it worked well and acted as a sleepy time que.
In Tracys last book, she says that flailing their arms and legs is not a conscious action, but usually a sign that they are having trouble in settling themselves to sleep due to overstimulation or over tiredness.
Hope this helps a bit.
