Ladies help me out here please! Any information will be appreciated 🙌

So my baby is 8 months(no crawling), she has her 2 bottom teeth cut through. Since a week ago she has not been herself at all 😭 ever since she was born she has been a great sleeper in her crib waking up once but now its 4 to 5 times, she cries, fuss and scream. Its really hard to get her back to sleep. She is no longer been breastfed since 6 months but now being in my boob is the only thing that comforts her. Also its really hard for her to actually get to her naps during the day. I know this is not much information to actually know what's going on but anything will be appreciated.
