We've been battling early wake ups for most of the past few months. We've tried lots of things, and LO will often not sleep past 5:30am. She is often clearly tired in the morning. For the past few days, she has taken extremely short morning naps totaling a half hour or less. I know that she can't be ready to drop her morning nap yet. Is this just a sleep regression? Luckily her night sleep is still good.

Any insight would be helpful. Thanks.
