if your baby is like mine then you'll need it in a way. he hates getting his diaper changed and the warm wipes make him not scream as much.
It's not a must have but its cool . If you leave it plugged in all the time regardless of the mist option I notice it dries out the wipes .
I don't wanna get one for my baby cuz if he's used to warm wipeys at home, I feel like when we're in public and they're cold he'll scream his head off lol
I decided not to get one because a couple people I've talked to about it say it dries out the wipes. But i have no personal experience so idk lol
I have one and just play with it bc she isn't here yet and love it lol so I'd say yeah
If your baby hates cold wipes or wakes up at every diaper change then no, u will want them to have it to get thru those midnight diaper changes.
