Girls, can you tell me if disposable diapers are really necessary for a newborn? The older generation says they're only needed in the hospital for themselves. They say that they will irritate the baby's skin and leak, so it's better to use cloth diapers. I initially wanted to stock up on these diapers as a reserve, but I was knocked off my feet ? It would be interesting to hear from experienced moms ?
