I started to let my little one to popo on the toilet every morning, because he is quite used to popo after his first bottle of milk in the morning, so it's quite easy to handle. But it's quite hard for his vv as it's not regular, don't know when he'll vv.
I think it's still too early for him to quit diapers, maybe wait until after the winter. I will let him take off the diaper at home during the day and teach him to go toilet. His elder brother quitted the diaper in 2 days, hope he could be as easy as his elder brother.
