Anyone using a swing similar to this one to make their baby sleep? My newborn only sleeps on this during the day when he’s more up, active and sometimes fussy. I just don’t know if it’s good to use this for long periods and I’m concerned if the continuous swinging motion has an effect on him. I tried putting him on his crib after he falls asleep on his swing but he would wake up and cry. He doesn’t like the swing to be stationary too, he prefers it in constant swinging motion.
