I don't have a miracle blanket. But I purchased a woombie for Christmas and really like it. It's not a super tight swaddle, but it still works for my LO and her startle reflex. I like that it zips from the top and the bottom. Also it's really easy to use. My dad prefers it, because it's easy and straight forward.
I just found a hand me down miracle blanket I didn't know I had. Dd slept 6 hours the first night in it, then I couldn't find it bc dd1 put it in her backpack and slept less the next night. Last night I put her in again and she slept 8.25 hours! Then another three. So I'll swear by it and hope it wasn't coincidence and this continues.
Re: swaddling products
I've never tried a woodbie, but I swear by my miracle blankets. Used them for both girls and love them.
This.
