Frustratingly normal!

Sometimes what works is making it fun and a team effort! 'DD you're a stinky bum, ewww so stinky!!' DD laughs. 'Can you go get me a nappy?' (She loves to have job to do). 'Ok, can you lie down'. 'Can you hold the wipes for me?' etc etc.

Or sing a song like a crazy person.

Or give her a ball of scrunched up sticky tape to play with. Really!
