Has any used one of these?

[chipo]

Am thinking of buying this for my dd as she likes sleeping swaddled, has anyone had any experience using it?

I would but she wriggles out of sheets, blankets, anything. if she isn't swaddled she wakes up arms flailing.

Have you tried use a grobag DD hated being swaddled and hated blankets she slept much better in it.
