My DS is 7 and a half months and is getting very fidgety when sitting down.. he just wants to get moving. If you hold him he just wants to jump and do something.
He can stay on his hands and knees but doesnt rock or try to move - although i'm sure the thought of it is going thru his head!
But he isnt rolliing over much... he can roll comfortable from his back to his front, but the other way he doesnt know to move his arm, he can but more by chance!... is this normal that he's working out how to crawl but still hasnt mastered rolling?
