Was just wondering if anyone else experienced this? Is it 'normal'?! 
She is really good at it however! We have nappy off from wake up to naptime and she uses potty with no prompting, but just stands over it weeing? Have tried several times explaining 'sit down on potty' she's very astute so knows mummy sits down on toilet to wee, and she's an only child, and Daddy at work til 5.30pm so not copying boys.. Have also tried sittting dollys on the potty and just got a weeing doll and potty yet to be tried so that may help. Whenever I've tried physically sitting her on it she struggles to get up and seems a bit scared...? Lord knows what we'll do about poo's! 
Its not a major issue, I'm sure she won't still be doing it as a teenager! More interested to see if its common, and any tips to 'encourage' sitting down! She's shown interest in sitting on the toilet a couple of times, but last time sat there with arms tightly round my neck and a bit scared! Not attempting to wee just testing it out I think!
