My current nanny has a very bright – and very big – Vera Bradley diaper bag. She takes it with us on overnight trips, which are infrequent.
The last time she had it along, a hotel desk clerk (I'd guess she was in her late 20s) asked, "Isn't that a Vera Bradley diaper bag?" My nanny answered that it was.
I was waiting for the "Where's your baby?" question that would surely follow, but it didn't.
When we're out on 'field trips' around town, she carries three or four diapers and wipes in a Vera Bradley crossbody bag, which doesn't look much like a diaper bag. I'm changed in the family restroom; we do get some strange looks from parents with kids in tow as we leave, but I can live with that.
