My twin DDs (2.5) have been using a potty in the day for the past two weeks with no accideents so far. One revels in using the potty and will happily do No1s and No.2s; the other will happily do a wee but is very reluctant to do a No.2. She cries and holds it in for as long as possible. When she's placed on the potty afer showing signs of needing to go, she will go but gets very upset. When her sister goes she makes a big show of saying how disgusting and smelly it is. She hasn't got this from us so clearly just thinks poo isn't very nice and doesn't like the feeling of going. Will she grow out of this and is there any way of encouraging her to get over the poo issue? I've tried a star chart this week and while the happy pooer is delighted by it, the reluctant one doesn't seem to care about the stars.
