dont worry. any age is never too late. my girl is 2years 4months and go childcare too. since she could communicate and understand, i bought the potty step stool for her and let her excitedly climb. and slowly tell her to pee and poo inside. but i feel its kinda confusing for her as most of the days she is in childcare and only use potty at hm. its quite interesting to see her calling to say she wants to pee in toilet bowl. but sometimes when i realise she wan to poo ill just rush her to the toilet bowl. she has managed to do a few poo and pees inside thou.
