Major sleep troubles

Anyone else having serious issues with sleep all of a sudden? At about 10 months she started taking crummy naps and about a week ago started totally resisting naps altogether. Maybe forcing 45 mins once a day. And bedtime has gotten worse and worse too. Been waking up at about 4am for a couple weeks and last night was up most of the night, she’s gotten 7 hours in the last 24 and we’re really struggling. Anyone have any help? I broke out the swing for her to nap in today that we put away at 6 months and I would hate to start that habit again but we need sleep. All of us. Help.
