DD is 16 months and in bumgenius (which I love, or used to!) in the last two days she has realised that she can take them off, she just grabs the sides through her clothes and pulls, velcro releasse nappy falls down and she runs off laughing. It does seem to co-incide with a forthcoming wee/ poo. She normally wears dungies or trousers so it hasn't been a problem before. I bought some pants to go over the top, but she can still loosen the nappy to a dangerous extent.
So far I've just been calmly putting the nappy back on so as not to make a game, but it's not working so do I a) tell her off and be (pretend) cross b) use pins or something or C)is she trying to tell me she wants to be potty trained. (she did sit down on the potty yesterday and do a wee, but I'm sure she isn't 'ready').
Any ideas?
