It wasn't too bad. If you have a baby who sleeps fine, I'm sure there will be few problems. My DS has never slept well, or fallen asleep easily so we had to use motion after he no longer used the hammock and rocked/bounced him in the ergo until he fell asleep and would then transition to our bed. Must say though, he did not need motion because of using the Amby - we bought the Amby because he needed motion to sleep.
