11 month old won’t sleep amymore

steph

Our 11 month old for the past two weeks has completely stopped her routine. No matter home much we try to continue her routine it just won’t work anymore. Now bedtimes take 4 hours from start to finally getting her to bed. Then she wakes up at 3:30am-5am then goes to bed and wakes up at 7:30am. She has either 2 or one nap a day. We talked to her doctor she says it related to teething. But we have tried everything we sat soooo tired. What do we do?
