Swaddling Question

Just wondering what age your baby was when you stopped swaddling/wrapping and how you went about it?
My wee girl is 3.5 months and wont sleep unless she is wrapped. And she is a great sleeper so not knocking it!But she is going into a cot this weekend so thinking it might be time to start thinking about getting her out of this habbit. I put her in a sleeping bag last night and wrapped her loosley over the top, she woke at midnight with her arms stretched out in front crying her eyes out. Not sure whether to keep life simple and carrying on wrapping until she grows out of it (hopefully!) or make some changes now?

Mine stayed swaddled til about 5 months I think, til she was ready to be out, lots of kicking legs and wriggly arms trying to escape, will still only tolerate a sleeping bag no covers at all

Mine wouldn't stay swaddled - she was a little Hudini - still is, so my friend's mum made me a few sleep sacks similar to the woombie - maybe if you are able to make/or have them made. It is pretty much like having a pillow case with a neck (I know hard to explain) - but it gives them enough room to move without getting to the face as their hands are still covered

My four-month-old is still wrapped, and will be until she absolutely has to be weaned from it. In my son, that was when he learnt to roll in his wrap and ended up face-down with no way of rolling back (about five months). If figure if they like it and it works, use it!
