can someone please help my little girl is potty trained for wee's and is full potty trained at night! she will do a poo on the toilet but when she does she starts crying and will not stop. I tried everything telling her its ok don't worry that's she's a big girl and everyone poo's on the toilet that its a good thing! anyone heard of this before, also the big problem is nursery because she will not go for a poo on the toilet only in her nickers??????????
