Baby swing

Dee
My DD is 5 weeks & I go back to work next week. I've been in a serious hunt for a swing for her & would like u all help/input. 
I would like one that:
Will last at least til she's about 6 months 
Has music
CAN OPERATE ON ITS OWN😫
Plug in option
But too bug(we're in a 1bdrm apt)
Not this one, I bought this and returned it because she seemed too big for the seat. She's 9 pounds 21 inches long.
Please help & thanks in advance!.
