I got this swing that rocks and vibrates for our family room (baby can also nap in it). I still need to get a pack n play for our first floor and possibly for baby to sleep in our bedroom first few weeks and don't know if I need the one that has the removable bassinet that vibrates since I have the swing.  Do you think I'll use both the swing and removable bassinet or should I go for a cheaper pack n play with the changer only?  Thanks!
