Unswaddling

Emma

So we've unswaddled baby because she has started rolling quite a bit. However she doesn't sleep for long stretches anymore with a sleep sack. (We tried one arm out and it wasn't helping) .Not sure whether it's only the unswaddling to blame or the 4th month sleep regression. She's barely just 4 months.is the magic Merlin suit really worth the money or should we just wait for baby to adjust? It's been 10 days maybe.
