I have always heard BRAT-Banannas, applesauce, rice and toast for D.
I have not liked apple juice nor its smell, since my daughter was a baby. I stopped breast feeding too early, mostly due the work associated to buying and moving into our first home (I was not working so I did all the make ready stuff including painting etc.)
She went to formula and did OK, when she started to drink milk, I discovered she was lactose intolerant--not a surprise since I am at least a fourth Native American--but not thought of in time to go back to breast feeding. With every episode of D she started on apple juice and cereal in applesauce until she got better.
It was probably not sweetened applesauce, esp since she did Ok on it.
