Is is possible that my dd uses the toilet at school and won't at home?

[CreepyCrawlyCarmenere]

Yesterday on the way to school dd(2.8) was passing wind, usually a sign that she neded to go to the toilet. Now she is not trained(not ready imo) and wears pull ups but she will sit on the toilet and does know that she should go in the toilet. Her pre-school won't change nappies so I told her from day one that if she neede to go she should tell the teacher like the other kids.
So yesterday I said on the way to school do you need to poo and she said yes, I tell teacher, so I said fine and told the tweacher when I dropped her off that dd needed the toilet. I fully expected a call to come and change her but it never happened. and when I changed her for bed her pull up was bone dry. So I asked her did she go to the toilet in school and she said 'yes, I ask teacher and go to toilet, like the other kids'.
Now is there any way possible that my dd is actually using the toilet in school and not at home?Obviously I will ask her teacher on thursday but.....

Dss has just told me that when I was away recently for 4 days they were worried because dd hadn't done a poo. Now the fact that she may have done in school makes more sense. The little madam!

Of course she is!

DD used to go to the loo on her own at cm but insisted she needed me at home. I found out 4 months later that she was going alone at the cm!

My DD (3) will go to the loo all by herself at Playgroup and Nursery but just wees everywhere at home
