What is happening

Yesterday my 11 month old didn’t have any bottles the entire day at all until 7:00pm and then when we tried to make her sleep she wouldn’t stop crying because she wanted another and had it at 8:00pm then she woke up at 10:00pm for another and then 12:30am and then 3:00am !!! I don’t know why or what to do ! And today it seems like she’s doing the same. I keep offering her milk but she just pushes it away and today she keeps gagging just from looking at the bottle teat when I offer it???? Help me
