Why would you want to give top feeds if you are getting enough milk through the day ? Why not give it at night too . Breast milk is safest and healthiest option for a baby . If u are lactating well better to give exclusive breast feeding . Diapers are no problem as long as you regularly change them so as to avoid sogginess of the perineal region and the resultant fungal rash . I would still advise cotton nappies in the day since they allow the baby’s skin to breathe and minimize possibility of fungal rash .

Try to give breastfeeding at night as well U can use diaper at night
