That is something I forgot to mention too Leash is that I only ever change DS overnight when he has pooed. He is in disposables (huggies - don't know if that makes a difference), he has had nappy rash maybe twice & only for a day or so I put on some lanolish stuff you use for your nipples & works a treat. I know when they are little they do poo overnight but that should settle soon. I stopped changing him overnight cause it would wake him up & make it harder to settle. Now he wakes up, I put him to the boob asap & he goes to sleep drinking, most times he doesn't even open his eyes.
Hope you sort out a compromise soon
