Baby girl playing games with me

Sophia is five months now. She'll be six months a couple days after Christmas. She loves to get me all excited and act like she's going to do something then don't. Like holding her bottle. I know she can do it but she won't. When did your children finally start to roll over and sit up? Anything I can do to get her interested in it?

    She is usually laying down. I'll do tummy time and roll her over or have her sit up in my lap or proped with pillows. I started putting toys around her to she if she would try to get them but she just went for the that was close to her. I even try to get her to hold her bottle. I'll put her hands on it or set it on her belly. Tell her good job when she does.
