I need advice on how many diapers to bring for my daughter. She is almost 3, and we havent trained her because of this trip, although I know she could if we did. Anyway, we went to Phoenix a couple of months ago, and she didnt use any more than she did here even with all the drinking she did. Should I pack 5 per day, more or less? Im finding this diapers take up most of the suitcase!!
