Hooray for Bilby Gigi, thats fantastic and I love your phrase 'disgustingly healthy'! just great lol
It does take longer for kids to get used to poos on the potty, its a bit weird seeing a mass of something in there rather than just some 'water' lol. At kindy, we had heaps of kids who would tell us they wanted a nappy on to do poo, and thats fine - they'll eventually get to a point where they dont like the feeling of poo in their nappy and would prefer to do it on the potty/toilet. So if thats what Bilby wants to do then just roll with it.
evie cries when she does a poo on the potty and usually asks for a nappy instead...i think its better to put a nappy on them than to have them hold it in
