And I'm speaking as a jungle main, do not in any circumstance hard push your laner's wave when they are on the way back from a recall and you haven't done anything to help them all game. Your action will force your laner to either lose two waves worth of cs when they're behind or risk a gank when trying to cs. If you want to farm the creeps, last hit them.
I'm sure everyone here has been in a situation where they have been counter picked, zoned by the enemy, had no jungle help and the only chance you have to farm is cockblocked by your own jungler pushing the wave to the enemy turret for you to be zoned the next few waves. You know how frustrating that feels, so don't do the same to your laner when you jungle.
