Sometimes health care providers will incorrectly inform you that you’ll need to swap to disposable nappies after immunisations. But you don’t!
After immunisations, or any illness, just ensure your main wash is at 60c (it should be anyway for babies under 3 months). And of course wash your hands throughly after changing nappies or handling the dirty nappies.
You’ll probably be extra thankful of the superior containment after the rotavirus.
