Has any other 10.5 month old done this?

So my son has gone on and off with babbling since about 5 months. I have been told it’s learning new skills and taking a break from some others. Which is fine with me but since he has hit months he is super whiny. And I’m confused a bit by this I’m a first time mom so forgive me for not knowing if this is something I should. And instead of babbling as much he’s switched to more whining and doesn’t want to be put down.. which he’s a chunk right now and it’s killing my back. But is this normal that he is whining a ton and making sounds and the babbling is not as much again? I’m trying to figure out what more I can do to encourage him to babble. I read to him and try to talk to him... I’m a bit of an introvert so something I forget to explain things I’m doing but i am trying. And I sing and play with him. I’m just not sure if all this whining is ok? He was a super independent baby and now it’s seemed to change a bit
