Does its motor make a lot of noise? I bought the Graco Sweetpeace because i was at my wits end thinking DD NEEDED a swing ASAP because she has been so fussy, and it was what BRU had. But its motor is soo loud, while she likes it, its driving me mad! I'm debating returning it and getting the Zen from BBB (Its what I wanted and registered for, but nobody bought it for me), but only if it doesn't have the same loud motor issue. TIA!
