What unusual item were you glad you packed in your hospital bag?
Disposable toothbrush: a toothbrush I'm willing to use for a couple nights then throw away at the hospital before I return home.
A lightweight robe. Cozy and comfortable, presentable enough for wearing around the hospital, and easy nursing access.
Favorite baby teething remedies?
Teething biscuits (watch closely to make sure baby can't ingest any small pieces that may break off)
My kids got relief from chewing on a wet washcloth we had kept in the freezer.
