Can someone explain this?

I dont get it. My baby who is now 1year and a month. Has slept on her own since day 1. She went from a bassinet to a crib of course always in our room. Now that shes at this age she HATES her crib. Her routine has always been the same bottle then sleep. Now she wilk drink half of it and get up she will be there for a few mins and starts crying wanting me to take her out. Idk why all of a sudden she hates her crib shouldn't she be used it by now? Sometimes she wakes up around 2 or 3am and starts crying get her out and there she goes to our bed. Knocks out. Let me say her sleep has changed alot. That girl is an early bird now 🐦😴
