Started with 'big boy pants' and a potty with my 2.5 ds yesterday afternoon. Made it into a bit of a game, set the kitchen timer for 15 mins and told him when the timer goes off he can sit on the potty and if he does a wee he gets a choccy button and if he does a poo he gets a freddo. First time he refused to use the potty when the timer went off and promptly wee'd on the carpet a couple of mins later. But since then he's been on the potty every time! Left him in his night time nappy while he had his milk this morning, but since then he's had a bare bum and been telling me when he needs a wee wee on the potty and he even did a poo in it this morning! Am so chuffed! (But not looking forward to the next few weeks of having to constantly be near to toilets or have potty with me!!! he he.)
