Can this be made for a child?

[ignora]

I've been searching for a sweater dress pattern for my daughter. She loves wearing dresses with tights. I've had good luck with the "long tank top" kind, but I also wanted a winter one with sleeves. I found this adult dress, which I love...

... but not for me (I'm much too round). But, it would gorgeous on my dd. I'm wondering if it would be possible to make it smaller... around a child's size 4/5. And, if so, how would I accomplish that?

And if converting this pattern is almost impossible (or just a giant PITA), does anybody know of anything similar that's already designed for a child?

TIA!
