Buying Diapers first before delivery?

Sign up with all the diaper brands/go to the next baby fair to get samples. All the newborn sizes for each brand have different cuttings/fit. Perhaps buy one carton of NB size of your preferred brand first then see if it works well. Even within the same brand, eg. Huggies Platinum and Huggies Gold, the size/cutting for newborn size is quite different. For my baby who had really skinny thighs initially, most brands would result in leakage at the thighs. Huggies Gold, Mamy Poko Air Fit and Drypers had a tighter fit. Merries, Pampers and Huggies Platinum had bigger cuttings
