Pattern needed

hi, I want to knit a baby cocoon and found one but am unable to find a pattern similar to this. I googled and found few but they are not with hoodie. Does anyone have a similar pattern?

That’s very cute. I think of it as a baby bunting and if you look it up on Ravelry (free to join), there are several pages. Some of them have hoods, too.
