If I don't swaddle sidney (4 months) her arms flail all over the place when I put her down in her crib and it is constantly waking her up. I figure that I can't swaddle her for too much longer (she is getting sooo strong that she breaks free from her miracle blanket plus she tries to roll while swaddled!!!)

Did anyone continue swaddling at this age and when does this reflex subside???
