Relapse! Help?

[Letitgoletitgo]

So dd 2.5 started potty training approx 3 months ago - much earlier than DS had done but instigated by her. Been completely dry and in pants for about last month, including finally being able to stay dry at playgroup and use toilet there.
Over last couple of weeks we seem to be having a wee relapse. Always at home, she's fine when out. She forgets she needs to use the potty, and just stands and watches it pour out through her clothes onto the floor, often right next to where the potty is! I've tried going back to reminding her, but she always says no she doesn't need it, and is very annoyed and resistant when I insist she sits on the potty (often manages a wee though!)
Any thoughts to stop this? Or do I just have to live through it?! And should I be telling her off or just brushing over it? Thanks!

It sounds like there might be something else going on if she was fine before. My friends little girl did this and it turned out she had a bladder infection. Might be worth double checking with a gp?
