8 month not holding her bottle

Hi mommas! Is anyone’s baby not holding their bottle yet at this age?? I’ve been still holding it for her and I’m guessing that’s why she won’t attempt to hold it herself. I take her hands and try to get her to but she won’t. She will pick up bee sippy cup by herself though and drink her water..I just have to help her keep it tilted up bc she doesn’t quit understand she has to hold it up to drink. What can I do to get her to start holding her bottle? Thanks ladies!
