2 year old and a new baby

Does anyone have tips on getting their two year old to understand that the new baby is fragile and they cannot do forward rolls onto them? My two year old does that on top of trying to poke her eyes and tell me they’re her eyes and isn’t careful around her at all. Any advice would be helpful:) we make sure the 2 year old gets one on one attention a lot and we also try and give him tasks that have to do with taking care of the new baby to help him understand but we still have a lot of problems with him jumping around her and almost hurting her on accident.
