Mich,
my gal's toilet training is very easy, i started with putting her on the toilet bowl and potty. (either) without pampers. i'll bring her to potty every 15min. as she grows to understand, i'll ask her if she wants to shiishii. if she said she don't want, then i'll not put her to potty. but last time when she said she don't want, 5 min later, she pees on the floor. hahahah
so, she knows it is not comfortable. so as days passed, she knows she has to go to her potty. she cant say shishii so she say ngggngg. so pee or poo, she says nggngg.
