A newborn gift idea could be some newborn diapers all folded into a three tier cake. To decorate it you can put some small baby items around the cake to decorate it. Maybe some baby rattles, teething rings, baby diaper pins and more. I don’t want to go on forever but this is a beautiful gift to give the mother of her newborn child. The fact that you took the time to put something together like that says a whole lot to the mother.
