The transfiguration won’t last forever if he leaves it on its own.
I’m not sure if this means that he actually has to have it on his person at all times, or if he just has to go near it every so often. Maybe he transfigured her into his blanket.
I would have guessed he’d have used the pouch, although Dumbledore can apparently search it without Harry’s permission, so that’s risky.
