DD is 20 months and showing serious signs of wanting to use the toilet. She knows what poo and wee is, is aware of the sensation of weeing and even got her toy Bert, put him in the potty, says "do wees" and "good girl"

My question though is how often should I be taking her to the loo? She doesn't pause when she's going, makes no signs of it. When she shouts out "Do wees toilet" I take her. She might say this 2 or 3 times in a day. She doesn't nap during the day, so I can't take her when she wakes up. TIA.
