Am in middle of second attempt to train DS2 who is 26 months. He asked me to bring the potty in the other morning so think he is ready for training. He knows all of the steps : use potty/wipe/empty potty/flush/wash/dry hands and gets rewarded with a sticker and a raisin (which he adores). He has done plenty of pees and even some poos in potty and received huge praise for it. However he now seems on a bit of a power trip and is refusing to sit on the potty at all. Just stands in front of you and deliberately pees on the floor, then laughs and runs off. Have just been saying " try and get it in the potty next time" but he just laughs again. ARRGGH!! Hes only 2 and hes already the boss. Any advice? Thanks
