I heard that in order to successfully potty-train, better to let them have a feel when urine run on her legs (keep an eye on her, cos' kids also like to play with "water"). Kids won't like that. After repeated try, kids have a sense to wee wee on the potty.
At home, better let her sit on the potty every 30 mins. I don't think 在家俾紙尿褲著 will help in the process. At home, just put on underpants and panties. You've got to buy a dozen, cos' will get wet 4-5 panties at the beginning. We can talk over the phone.
