Bouncing

Anyone else's 6.5 month old baby still not have the hang of their doorway bouncer? Mine will turn, stand on her tippy toes, and play, but she has no interest in bouncing. I have seen her bounce in it, but it is not consistent at all. She doesn't bounce in her exersaucer either. She is developing normally, can bend her legs, and is super close to crawling, so I don't think anything is wrong. Hmmm...
