DD is 2.5 and generally a good sleeper. Her latest thing though is if she becomes uncovered in the MOTN she wakes up and screams until we go retuck her in. She wakes up at least 3-4 times a night because of this and it's driving me crazy! Any ideas on how to fix it? She's still in a crib and refuses a sleep sack, so she just has two toddler bed size blankets. I considered putting a twin comforter in but am worried it'd be way too big / a hazard.
