Hi there
My little one was swaddled from birth (she is six months now). I used the miracle blanket. When she got to about three months she started to struggle and get one arm out. So I took that as I sign that she ready to start being weaned out of it. I wrapped her with one arm out, for day and night for about a month, I really took my time over it as she was a very good night sleeper and I didnt want anything to disrupt that too much!! :shock:
Anyway, she too was a big finger (and now thumb) sucker, so she loved it. After the month, we braved it and put her down with no swaddling at all. She only woke once as normal for her night feed and havent used the swaddling since.
I would go for it. If your little one is sucking through the swaddling, chances are you should have few problems. I think they get to a stage where they like the freedom to fling themselves about a bit!!
Hope this helps.
