i change her as nessacery. sometimes changing can be challenging. car rides and shopping trips with less than sanitary bathrooms, besides not having a changing table. the idea i go with: would you want to sit in a pair of wet Depends all day? The only exception i find is that babies who sleep through the night will be very wet in the morning. just change your baby when they are wet and you are golden! rule of thumb for me is before every feeding and after every nap.
