When will my baby sleep through the night without fussing?! 😴 I been putting cereal in her bottle before bed she goes almost 8 hrs without eating but wakes up fussing for her

Binky and moving around a lot, then I give her binky back and 5 min later she's moving a lot it falls out and she's fussing again. She's 2 months. Anything I can do or is it normal and she will grow out of it?
