Both our sons hated swaddling as we were doing it, but slept well while being tucked. The older one needed it until he could roll over safely and sleep on his belly (probably around 6 months for him). He outgrew the large SwaddleMe, so we had to wrap big recieving blankets around it to keep him tucked in. Whenever he got his arms out, he would hit himself in the head and cry. The younger one started out being swaddled, but always ends up w/ the blanket over his head or completely seperate from the SwaddleMe, don't ask me how he did it. We had all intentions of swaddling the younger one for as long, but he doesn't need it. He's almost 5 months old and sleeps through the night in just pjs.
So I'd keep her swaddled. If it helps her get a good nights sleep, which in turn helps you get a good nights sleep, than keep it up.
Good Luck!
